Monocoque technology. Composite technology: Molecular structure Less maintenance, more enjoyment

Stefan Winkelmann, head of Lamborghini, shared: “ The outrageous top speed, like the superpower of the engine, is no longer a priority for us.". These words were shocking at first. But then he quite clearly described the further priorities of the company headed by him: “ The record-breaking dynamics and phenomenal handling of supercars will not be affected by our new design approach. Understand, 300 km / h maximum speed is already a generally accepted norm for any modern supercar, but where can it be achieved? Only on race tracks for a very short time. We will not continue to increase engine power for environmental reasons - Lamborghini, like all other cars, also needs to fit into the CO2 emission standards. But there is a way out - to achieve a record ratio of power and weight of the car. There is only one way - the large-scale use of CFRP. Formula 1 race cars have long confirmed that we cannot find a better material that combines strength and lightness».

This is how, at once bringing down the old values, Mr. Winckelmann led us to the main purpose of our visit to the Lamborghini. From now on, this company is the only automotive company in the world with a division for the development, testing and production of carbon fiber parts.

THE HAND OF WASHINGTON

Lamborghini would not have been able to cope with a project of this magnitude alone. Financially (and to some extent technologically) she was helped by Audi, the current full-fledged owner of the Italian firm within the Volkswagen concern. The Americans helped out with the selection of materials, technologies and computer simulation of crash tests of carbon elements for the new flagship - the 700-strong Aventador. Mostly the University of Washington, known for its research in this area. The establishment has considerable experience, mainly thanks to its joint work with Boeing, which is launching the Dreamliner, the first passenger aircraft with a composite fuselage.

The aircraft manufacturers also shared their know-how with the Italians - a method of quickly determining the degree of damage and prompt repair of carbon fiber structures. After all, an aircraft with a problematic element often cannot be sent under its own power to the manufacturer. Boeing has created an institute of "flying doctors" - qualified repairmen with "magic suitcases" that have everything you need to study the nature of damage and repair it. Similar guys will fly to unlucky Lamborghini clients. To reduce the arrival time, three points of deployment of carbon doctors were organized - in Italy, the USA and Australia.

At the same time, the University of Washington took over the promising development of carbon fiber technologies. And he married Lamborghini to another very unusual partner - Calloway, the world leader in golf accessories. It makes carbon fiber golf clubs by hot stamping using carbon fiber blanks with very short threads - from 2.5 to 5 cm.But thanks to their high density (more than 200 thousand fibers per square centimeter), the tips of the golf clubs are extremely durable.

Lamborghini has already tested this technology on the body and suspension elements of the Sesto Elemento concept car. It turned out well, but serious tests must precede serial production. A supercar is not a golf club, even a super-tech one.

AND WE FAST ON A SLOW FIRE

And what technologies are already being used to create Aventador? There are now three different methods in use.

The first begins with the formation of future elements by stamping. Carbon fiber blanks are shaped like ordinary sheet metal, and then placed in special conductors, where, under the control of laser meters, they are joined together, with tolerances of no more than 0.1 mm.

Further, a polymer resin is injected between the elements under low pressure. The process ends with sintering in a thermal chamber. There is a minimum of manual labor in this process - most of the operations are assigned to automation. Expensive autoclaves are also not needed - there is no need to maintain a certain pressure.

The next method is, in fact, a variation of the previous one. The only difference is that here the layers of carbon fiber intersect with each other - this is how the most critical power parts are formed, for example, struts and body reinforcements.

A radically different method is needed to make parts with a perfect outer surface. In this case, chilled carbon fiber preforms are used with a pre-injected heat-sensitive resin that reacts when the temperature rises. Such elements are laminated with a film after manual surface molding in a matrix. After that, vacuum devices remove the smallest air bubbles from under the film, leaving a flawlessly flat surface. The elements are then placed for final curing in an autoclave, where they undergo a heat treatment for two to five hours.

This is how, step by step, the monocoque elements of a new automotive legend are born. Moving from line to line, they are overgrown with new details, strengthened in critical places with epoxy foam, which, filling the voids, also serves as sound insulation; they are implanted with mating aluminum parts for attaching the front and rear subframes. It is interesting that already made elements often serve as the initial matrix for subsequent ones. They are even baked together - this significantly reduces the time and cost of intermediate operations. The climax is the connection of the lower base of the load-bearing structure to the roof. The result is a carbon monocoque weighing only 147.5 kg. The aluminum frame with carbon fiber reinforced plastic elements "Murcielago" weighed 30% more - with less rigidity one and a half times.

By the way, the predecessors of "Aventador" made 4099 pieces in nine years. The circulation of the novelty is supposed to be at the same level, that is, 400-500 copies per year. This is a breakthrough for a design with such massive use of carbon fiber. For example, the British "McLaren F1" 1992, the first-born of the serial use of the carbon body structure, was released in only 106 copies. But it also cost much more than the current flagship "Lamborghini". After all, then carbon fiber was considered an incredible, outrageous exotic for a road car - today it is still expensive, but it is already becoming commonplace.

HISTORICAL FACT - A SPELL OF SILENCE

Lamborghini does not particularly talk about this, but the fact is that a quarter of a century ago this Italian company already had a laboratory for the development and implementation of composite materials. It was headed by none other than the Argentinean Horatio Pagani, who later created the Zonda supercar. Appearing in 1999, the car impressed with the massive use of carbon fiber, including the load-bearing body base - something that appeared on the "Aventador" only 12 years later. Apparently, the successes of the former employee make the management of "Lamborghini" hush up this fact, although the production of "Pagani" is no more than 20 pieces a year and they are not an obvious competitor to "Aventador".

But Lamborghini never tires of repeating that their first car with an all-carbon monocoque appeared back in 1985. Again, no mention is made of Pagani, the main initiator of the Counter Evolution project. It was made only in one copy, but, in addition to the carrying carbon monocoque, that car received carbon fiber stretchers for attaching the power unit and suspension. The boot lid, bonnet, wheel arch extensions, rims and front spoiler were also made from a forward-looking material. The car has lost about 500 kg compared to the serial one - a huge achievement for a supercar. With a power of 490 forces, the car had phenomenal dynamics - it accelerated to a hundred in less than 4 seconds, and the maximum speed was 330 km / h - the serial "Murcielago" achieved similar results only 15 years later.

After 300 million years, carbon has returned to Earth again. It's about technologies that represent the new millennium. Carbon is a composite material. It is based on carbon threads, which have different strengths. These fibers have the same Young's modulus as steel, but their density is even lower than that of aluminum (1600 kg / m3). Those who have not studied at physics and technology will now have to strain ... Young's modulus is one of the elastic moduli that characterizes the ability of a material to resist stretching. In other words, carbon strands are very difficult to break or stretch. Compression resistance is getting worse. To solve this problem, they came up with the idea of \u200b\u200bweaving the fibers together at a certain angle, adding rubber threads to them. Then several layers of such fabric are connected with epoxy resins. The resulting material is called carbon fiber or carbon fiber.

Since the middle of the last century, many countries have been experimenting with obtaining carbon. First of all, the military were interested in this material, of course. Carbon went on the free sale only in 1967. The first company to sell the new material was the British firm Morganite Ltd. At the same time, the sale of carbon fiber as a strategic product was strictly regulated.
Advantages and disadvantages

The most important benefit of carbon fiber is its superior strength-to-weight ratio. The modulus of elasticity of the best "grades" of carbon fiber can exceed 700 GPa (and this is a load of 70 tons per square millimeter!), And the breaking load can reach 5 GPa. At the same time, carbon is 40% lighter than steel and 20% lighter than aluminum.

Among the disadvantages of carbon: long manufacturing time, high material cost and difficulty in restoring damaged parts. Another drawback: when in contact with metals in salt water, CFRP causes severe corrosion and such contacts should be excluded. It is for this reason that carbon could not enter the world of water sports for so long (recently they learned to bypass this shortcoming).





Another important property of carbon is low deformation and low elasticity. Under load, carbon is destroyed without plastic deformation. This means that the carbon monocoque will protect the rider from the strongest impacts. But if it doesn’t stand it, it will not bend, but break. And it will scatter into sharp pieces.

Carbon fiber production

Today, there are several ways to make carbon fiber. The main ones are chemical deposition of carbon on a filament (carrier), growing fiber-like crystals in a light arc, and building organic fibers in a special reactor - an autoclave. The latter method is most widespread, but it is also quite expensive and can only be used in industrial conditions. First you need to get the carbon strands. To do this, take fibers of a material called polyacrylonitrile (aka PAN), heat them up to 260 ° C and oxidize them. The resulting semi-finished product is heated in an inert gas. Long-term heating at temperatures from several tens to several thousand degrees Celsius leads to the process of so-called pyrolysis - volatile components decrease from the material, and fiber particles form new bonds. In this case, the material is carbonized - "carbonization" and rejection of non-carbon compounds. The final step in carbon fiber production involves weaving the fibers into plates and adding epoxy. The result is black carbon fiber sheets. They have good elasticity and high tensile strength. The more time the material spends in the autoclave, and the higher the temperature, the higher quality carbon is obtained. When making space carbon fiber, temperatures can reach 3500 degrees! The most durable grades go through several additional stages of graphitization in an inert gas. This whole process is very energy-intensive and complex, because carbon is much more expensive than fiberglass. Do not try to carry out the process at home, even if you have an autoclave - there are many tricks in the technology ...

Carbon in the auto world

The appearance of carbon could not fail to interest the designers of racing cars. By the time carbon fiber was introduced to F1 trails, almost all monococks were made of aluminum. But aluminum had disadvantages, including its insufficient strength under heavy loads. The increase in strength required an increase in the size of the monocoque, and therefore its mass. Carbon fiber has proven to be an excellent alternative to aluminum.





The first car with a carbon fiber chassis was the McLaren MP4. The path of carbon fiber in motorsport has been a thorny one and deserves a separate story. Today, absolutely all Formula 1 race cars have a carbon monocoque, as well as almost all "junior" formulas, and most supercars, of course. Recall that a monocoque is a load-bearing part of the car's structure, the engine and gearbox, suspension, plumage parts, and the driver's seat are attached to it. At the same time, it plays the role of a safety capsule.

Tuning

When we say "carbon", then, of course, we remember the hoods of tuning cars. However, now there is no body part that could not be made of carbon fiber - not only hoods, but fenders, bumpers, doors and roofs ... The fact of weight savings is obvious. The average weight gain when replacing the hood with a carbon one is 8 kg. However, for many, the main thing will be the fact that carbon parts on almost any car look insanely stylish!

Carbon appeared in the salon. You won't save much on carbon fiber toggle covers, but the aesthetics are beyond question. Neither Ferrari nor Bentley disdain salons with carbon elements.

But carbon is not only an expensive styling material. For example, it is firmly established in the clutch of cars; and the friction linings and the clutch disc itself are made of carbon fiber. Carbon fiber "traction" has a high coefficient of friction, lightweight, and three times more resistant to wear than conventional "organic".






Another area of \u200b\u200bapplication for carbon fiber is brakes. The incredible brake performance of the modern F1 is provided by carbon discs that can handle the highest temperatures. They can withstand up to 800 heat cycles per race. Each of them weighs less than a kilogram, while the steel counterpart is at least three times heavier. You can't buy carbon brakes on a regular car yet, but on supercars such solutions are already coming across.

Another commonly used tuning device is the durable and lightweight carbon propeller shaft. And more recently there was a rumor that Ferrari F1 is going to install carbon gearboxes on its cars ...

Finally, carbon is widely used in racing clothing. Carbon helmets, boots with carbon inserts, gloves, suits, back protectors, etc. This "outfit" not only looks better, but also increases safety and reduces weight (very important for a helmet). Carbon is especially popular with motorcyclists. The most advanced bikers dress themselves in carbon from head to toe, the rest quietly envy and save money.
New religion

A new carbon era has crept quietly and quietly. Carbon has become a symbol of technology, excellence and modern times. It is used in all technological areas - sports, medicine, space, defense industry. But ulevolokno penetrates into our everyday life! You can already find pens, knives, clothes, cups, laptops, even carbon jewelry ... Do you know what is the reason for the popularity? It's simple: Formula 1 and spaceships, latest sniper rifles, monocoque and supercar parts - do you feel the connection? All this is the best in its industry, the limit of the possibilities of modern technologies. And people, buying carbon, buy a piece of perfection unattainable for the majority ...

today, high-strength ropes, nets for fishing vessels, racing sails, aircraft cockpit doors, bulletproof protective army helmets are made from carbon
Arrows made of aluminum and carbon are usually used for long-range sport archery by professional athletes.

At the Essen Motor Show, we saw a freaky carbon ring on a finger on an AutoArt booth employee. When asked to display the product in his endless catalog, he replied that it was actually just a carbon hub that he removed from his bike ...

In the past, bicycle suspension was developed using a 2D kinematic model. Advanced Dynamics was developed in conjunction with the CEIT (Guipuzcoa Studies and Technical Research Center) based on virtual simulation and off-road cycling simulation programs with active front and rear suspension. CEIT is a research and development center that develops and tests the latest technologies for large industrial companies. Using this virtual analytics system, Orbea and CEIT were able to identify all the variables that affect suspension performance on descents, ascents and different types of terrain. As a result, it was possible to identify 4 key elements around which the development of the new suspension was built: a suspension that not only makes the bike more comfortable, but also does not deprive it of dynamics, the most efficient use of the full suspension travel, specially tuned shock absorbers and sealed sealed bearings.

Many other designers perform all calculations on paper or in a computer, but we have created your virtual clones. Our simulation programs allow you to recreate many different factors that affect the performance of the suspension: from the type of terrain, constitution and position of the rider while riding, to the distribution of loads on the pedals, saddle, handlebars, etc. Based on data from numerous studies, we've created a suspension that maximizes all types of shock absorption, minimizes swing when pedaling, and maintains consistent wheel contact with the surface you're riding on, whatever the terrain.



Attraction technology adds to your ride the comfort that many cyclists dream of. It is responsible for neutralizing vibrations that occur while driving and optimizing the load on the wheels, improving pedaling efficiency. This technology also improves the bike's handling and traction, regardless of type and weather conditions.

The redesigned Orca's fork and rear triangle have been redesigned to make the ride more comfortable and efficient. Attraction Technology is responsible for absorbing shocks that occur when driving on uneven asphalt without sacrificing torsional rigidity of the frame, thereby increasing pedaling efficiency.

Helps to achieve unmatched distance results

Thanks to the special profile of the upper stays, the vibrations that occur during riding are not transmitted to the rider, but are damped without reaching him, transforming from longitudinal to minor lateral vibrations. Thus, we managed to create a bike for competitions of the highest level, which fully meets the requirements of athletes who experience the hardest physical activity during races:

  • reduced level of vibrations transmitted to the rider while driving;
  • improved grip of the bike with the road surface (as a result, the rider will be able to make more efficient accelerations and sprint jerks, and at the same time the bike will be better controlled);
  • increased efficiency of power transmission to the rear wheel when pedaling;

Orbea carbon

The carbon that Orbea uses in production is a composite material made of carbon fibers with a high modulus of elasticity. We use it to create optimal frames in terms of rigidity, strength and vibration damping. These are essential characteristics to create the perfect frame.

We used our accumulated experience and advanced technologies to develop three types of fibers: Gold, Silver, Bronze... They differ in physical properties and, as a result, in their preferred field of use. Thus, all of our carbon frames are labeled as follows, depending on the type of fiber used:

OMG. Orbea Monocoque Gold

OMS. Orbea Monocoque Silver

OMB. Orbea Monocoque Bronze

One of the key differences between fiber types is the value of the elastic modulus (Young's modulus). The higher the Young's modulus value, the greater the rigidity of the structure and the lower its weight. Accordingly, each type of carbon fiber developed by us has a certain Young's modulus value: Gold - maximum value, Silver - high, Bronze - medium.

OMG. Orbea Monocoque Gold

OMG carbon is made up of fibers with the highest Young's modulus and has the best stiffness and weight. The use of such fibers, laid in certain layers, which in turn have gone through a multistage Finite Elements Analysis (FEA), allows us to create frames that have maximum rigidity with minimum weight. These frames are subsequently used in competitions of the highest level. We put cutting-edge technology into your hands.

OMS. Orbea Monocoque Silver

OMS carbon consists of fibers with a high modulus of elasticity. They give the frames sufficient rigidity, a high level of vibration damping and maximum pedaling efficiency over long distances. OMS carbon is made from a combination of fibers with the maximum Young's modulus and fibers that provide a high level of vibration damping.

OMB. Orbea Monocoque Bronze

OMB carbon offers you the optimal combination of fibers with a medium modulus of elasticity, yet elastic and durable. It is widely used in more affordable carbon frames. The higher density and resistance to compression of Bronze fibers increases their vibration damping properties and durability. This is because Orbea's engineers have always tried to exceed industry standards in their work. We strive to ensure that riders who discover Orbea carbon frames for the first time can get the most out of them and achieve outstanding performance and progress.

Monocoque technology

Orbea engineers have long understood that the monocoque is the only technology that can optimize the frame in terms of rigidity, durability and comfort. The video below shows how a traditional carbon frame degrades over time, while a monocoque frame remains as if it had just left the factory.

Monocoque technology also allows for more creative frame designs and good fatigue crack resistance. This is why we can provide a lifetime warranty on all our bikes: our frames are reliable and their performance does not change over time.

What makes Orbea's monocoque technology so special?

The overall strength and reliability of the structure is higher due to the optimal distribution of loads throughout the frame structure, the absence of welds and joints. This means that the frame will not let you down, regardless of the tests that the track prepares for it. Monocoque technology ensures perfect fiber bonding in composite materials not only in the outer layers, but also in the inner ones, which prevents fatigue cracks at the joints of frame elements. The latter problem is typical for frames manufactured using inexpensive and more traditional technology. Do you need any more arguments in favor of frames produced by Orbea monocoque technology? After all, we are dealing with a rigid and reliable frame, with decorative elements that will not peel and crack in high-loaded areas of the structure, with a frame that is a monolithic masterpiece of composite art, and not assembled from individual elements ... The choice is obvious.

UFO is a suspension system from another planet.

UFO is a carbon fiber suspension system designed to take the user away from traditional pivots and everything that goes with them: nuts, bolts, bearings and finally the axles themselves. The result is a reduction in frame weight and suspension maintenance time while improving overall structural rigidity and traction on technical terrain. Pro athletes need a lightweight yet optimally performing rear suspension: they seek the perfect balance. And UFO technology is ready to offer it to them: a suspension system that meets the most stringent weight requirements (frame with a shock absorber 1.95 kg), easy to maintain and reliable.

UFO technology allows for greater grip and torsional rigidity on technical terrain with low weight and easy maintenance

Benefits

Oiz carbon Is a unique bike in its class that uses a rear suspension system without a pivot axis. The perfect combination of stiffness and flexibility of carbon fiber results in a suspension that is resistant to lateral and torsional loads, which handles uneven terrain well throughout the entire 85 mm of shock travel.

As a result:

An innovative suspension system that provides confident control of the bikes on descents, pedaling efficiency on climbs, more comfort and less rider fatigue during long stays in the saddle.

SSN technology

SSN (Size Specific Nerve) is more than just a technology, it is a way of organizing work throughout the bicycle manufacturing process. At first this approach was used only for the development of models from the Orca line, but then we also began to use it for the Alma and Onix models.

Models from rulers are developed using SSN technology Orca, Alma, Onix and Opal

Formula for your needs

Each bike size is developed by us individually. Frame structure and stiffness are optimized relative to the rider's weight statistics at a given height. As a result, we get 5 (according to the number of sizes) individually designed and perfectly balanced frames.


AIZonE by Orbea

The AIZonE (Aerodynamic Investigation Zone) project was developed in conjunction with the San Diego Wind Tunnel (a wind tunnel located in the American city of San Diego) and allowed us to obtain many different data on the aerodynamics of bicycles and riders. This allowed us to improve the aerodynamic performance of the updated Orca by 14%. We have managed to reduce the force of air drag, and the result is a more stable and well-controlled bike.

Improved handling and stability by reducing clearances between the frame and the moving parts of the bike

Closing gaps between the frame and the moving parts of the bike (such as the wheels) is key to reducing turbulence. It occurs as a result of the fact that during movement the incoming air flow presses unevenly on the surface of the frame, components and the rider, forming vortexes. These eddies hit the protruding parts of the bike, slowing your forward movement.

Reducing the gaps between the tires and the frame surface minimizes the negative impact of the incident air flow. We designed our bikes with this principle in mind and ended up creating some of the most stable and well-controlled bikes on the market.

More speed thanks to the teardrop shape of the seat tube and post, inherited by the Orca from Ordu bikes

Orbea engineers identified two key metrics for a fast bike: frame rigidity and aerodynamics. Both of these characteristics are important in order to create not only a fast bike, but also the most efficient pedaling. The first sign of this paradigm was the Ordu model, but later it was applied to the development of other lines.

The water drop has a perfect aerodynamic shape, which we used to design the headset and seat tube on Ordu bikes. We used our research data to redesign the seat tube and post on the Orca to create the fastest bike in the peloton.

Reduction of resistance to the oncoming air flow (grams):

  • rear triangle: 14g
  • seatpost clamp: 17g
  • headset and fork: 15g
  • seat tube and seat post: 10g
  • down tube front triangle: 8 g
Total: 64 grams less resistance to oncoming airflow, which is the equivalent of 14% of the bike's surface.

DCR technology

DCR is the route of cables and hydraulic lines along the shortest route.

We have created and patented an exclusive and much more efficient than existing analogs, hydraulic lines and cables routing system. The main principles in its development were simplicity and accuracy. We have made it so that the cables do not interfere with you while riding, putting them in special aerodynamic recesses on the sides of the upper (and on some models of the lower) tube.

Less service, more fun

  • low maintenance system and more precise operation of brakes and switches;
  • cable shirts are equipped with special plugs to prevent dirt from getting inside;
  • goreRideOn coating reduces friction, extending the life of shirts and cables.

Fewer shirts, which means:

  • reducing the length of the cables;
  • reducing the total weight of the bike;
  • no scuffs on the frame.

What does Dama mean?

Dama stands for a special technological approach to the manufacture of frames for women's bicycles. Women are fundamentally different in physique from men, so bicycles should be special for them. First of all, it is worth paying attention to the fact that statistically, the weak half of humanity has longer legs and a shorter body than men.

We have changed the entire technological chain, from the selection of components and materials for the manufacture of frames and ending with the production process. Because the bike has to adapt to you, not the other way around.

Women have a special physique, so bicycles should be special for them too.

How is Orbea using data from multiple studies?

The dimensions of all tubes in the frames were reduced, with the exception of the steering tube. And the angle of inclination and location of the upper tube have been changed in such a way as to best match the features of the female anatomy. Orbea also uses specially designed components such as saddles and handlebars.

Saddles should be slightly shorter and wider than male models, and handlebars should be slightly narrower. Also, for tall representatives of the fairer sex, size 46 was specially introduced. Previously, none of the manufacturers did this, and the riders had to spoil their fit and health by riding unsuitable bicycles. The introduction of technological solutions from the Dama series is another step towards meeting more complete satisfaction of all the wishes of cycling lovers.

Lamborghini has unveiled the new supercar carbon monocoque. Lamborghini unveils new supercar monocoque In just two weeks, Lamborghini intends to unveil the Murcielago's successor, the LP700-4 Aventador. Weighing just 147.5 kg, Lamborghini assures that it offers optimum safety and high torsional rigidity.

Lamborghini continues to reveal a little more secrets about its new LP700-4 Aventador supercar, which will debut at the Geneva International Motor Show.

Engineers have shared information about a new composite monocoque that will form the core of the supercar. The entire structure is made of a durable composite material reinforced with carbon fiber (CFRP - Carbon Fiber-Reinforced Polymer) strands, and is designed to maintain its shape under excessive loads and ensure the safety of passengers. It weighs only 147.5 kg, while the mass of the finished body without painting and primer is 229.5 kg. In addition, the car has a "phenomenal torsional rigidity of 35,000 Nm / deg".

The monocoque is built using three complementary manufacturing methods - Resin Transfer Molding, Prepreg and Braiding - and includes a complex epoxy structure reinforced with aluminum inserts. More importantly, the engineers were able to simplify the manufacturing process and achieve amazing assembly precision - the distance between the interacting elements is no more than 0.1 millimeter.

As a reminder, the LP700-4 supercar will receive a 6.5-liter V12 engine producing about 700 hp, mated to a lightning-fast 7-speed ISR gearbox. Thanks to it and the Haldex electronic permanent all-wheel drive system, the car will be able to accelerate from 0 to 100 kilometers per hour in just 2.9 seconds and confidently reach a speed of 350 kilometers per hour.

Monocoque is a spatial structure, where the outer walls of the shell are the load-bearing element. For the first time, the monocoque began to be used in aircraft construction, then in the production of cars, and finally this technology migrated to bicycles.

As a rule, it is used to make the front triangle of the frame by longitudinal welding of aluminum extrusions. The shape and size of a monocoque structure can be made in a variety of ways, which is not always possible when using ordinary pipes.

This technology makes it possible to increase the rigidity of the frame and reduce its weight without loss of strength due to the elimination of welds from the points of the main stress of loads. Sometimes the anterior triangle forms one solid structure without gaps.

New Monocoque technology

This was the first time this technology was used on steel frames. Monocoque frames are also called structures where pipes are welded together in a separate section, and not along the entire length, for example, in the area of \u200b\u200bthe steering column or carriage. At the junction of the pipes, there are no walls between them, only a welded seam along the contact length, due to which weight savings are achieved without loss of rigidity.

Monocoque frames are also made of carbon. The creasing profile, combined with cabon fiber and carbon fiber couplings, results in a monocoque frame design that combines lateral stiffness and vertical resilience. As a rule, all carbon bikes are monocoque, because they are made in one go, and not from separate parts like conventional bicycles.

Using this technology, not only the bicycle frame is manufactured, but also other units: handlebars, stems, elements of the rear triangle of the frame, and others. Monocoque technology is quite expensive and is therefore used on high-end bicycles.
