Carbon Fiber
Carbon Fiber
I'm interested in making carbon fiber hoods and other parts in my garage, what is the best way to do this?
Carbon fiber hoods, building
I am interested in making carbon fiber products as a buisness. I am not concerned with cost or effort required for the process.
making carbon fiber stuff is very difficult. you have to get the material, make a mold, apply the resin, let it harden, and then bake it. carbon fiber isn't cheap...i just saw a program on carbon-fiber bicycle frames...whee! i was also thinking about how to start a CF business....
about the closest you can get to doing it yourself is to use fiberglass. there is a great, very long video of it being done on youtube.

At the 42nd Annual Meeting of Stockholders of Volkswagen AG in Hamburg, the most economical car in the world is presented: the 1-litre car. The prototype, which until now has been kept closely under wraps, and which many people never believed could be built, was driven under its own power from Wolfs burg to the Annual Meeting in Hamburg.
Before the Annual Meeting, the current Chairman of the Board of Management, Dr. Ferdinand Piëch, drove this research vehicle to Hamburg from the company's headquarters at an average fuel consumption of 0.89 liters per 100 kilometers. This has once against impressively demonstrated Volkswagen's position at the cutting edge of modern technology.
The objective of developing a roadworthy vehicle that consumes just 1.0 liter of fuel per 100 kilometers could not be achieved through compromise. All existing technical solutions were examined, and in close cooperation with numerous suppliers, replaced by better, and principally lighter versions. The result is a vehicle that looks more like a sports car than a typical research vehicle.
The conceptual necessity for a small frontal area led to an unusually narrow and very flat body form being chosen. The body was developed in a wind tunnel, is 3.47 meters long, but just 1.25 meters wide and just over a meter in height, and is made completely of carbon fibre composites. To save weight, it is of course not painted.
The carbon-fiber-reinforced outer skin is tensioned over a space frame that is not made of aluminium, but rather of magnesium, which is even lighter. The 1-litre car is powered by a one-cylinder diesel engine, centrally positioned in front of the rear axle and combined
with an automated direct shift gearbox. The crankcase and cylinder head of the 0.3-litre engine are of an aluminium monobloc construction. The naturally aspirated, direct-injection diesel engine employs advanced high-pressure unit injection technology to generate 6.3 kW (8.5 bhp) at 4,000 rpm. This gives the vehicle, which weights just 290 kg, an astonishingly lively temperament.
Fuel consumption is a mere 0.99-liter per 100 kilometers. With a 6.5-litre tank, this gives a range of some 650 kilometers without refueling. Due to the restriction of space, it was not possible to adapt an existing gearbox. For this reason, a compact, automated 6-speed gearbox is employed, which is controlled from a turn switch in the cockpit.
Running gear made of lightweight alloy, tyres that offer optimized rolling resistance and 16-inch wheels made of extremely lightweight composite material perfectly complement the economical drive system. The interior is sportingly simple in design, yet offers enough space for two people, who can comfortably get in after folding back the turret-like gullwing door.
An extremely lightweight construction has also been employed for the seats. The seat frames are made of magnesium, and firm, yet comfortable fabric covers are used instead of classic upholstery. Despite the lightweight construction of all components, safety has been a major element in all phases of the development of the 1-litre car. For example, the concept vehicle's safety equipment includes anti-lock brakes, ESP electronic stability program and a driver's airbag. Deformation elements at the front end and the space frame construction provide impact and rollover protection comparable to that of a GT racing car.
The sports-car-like design demonstrates that Volkswagen's 1-litre car is not a Spartan research vehicle, but a high-tech special vehicle. It starts with the special seating arrangement. The driver and passenger sit centrally as if in a monoposto, but in tandem. The mid-engine is installed transversely in front of the rear axle. With its complex design (double wishbones at front, DeDion suspension at rear) and combined with the low centre of gravity and low overall vehicle weight, the lightweight running gear results in very agile handling.
The project team has impressively succeeded in combining driving pleasure with a level of fuel consumption never seen before. The 1-litre car also incorporates numerous details of a practical and convenient nature. For example, there is an easily accessible stowage compartment with a capacity of 80 liters under a separate flap in the rear; a reversing camera that helps when maneuvering; automatic locking/unlocking of the gullwing door and a starter button in the cockpit that together allow keyless operation.
The concept of the 1-litre car - four wheels, low height, with two seats in tandem - gives an idea for a possible new family of vehicles, which could cover new requirements ranging from the ultra-economical vehicle, through the low-lost everyday touring vehicle for young people to the high-performance sports super car.
