Carbon

     Carbonic fibres are carbon filler. Carbons have well-defined characteristics in different areas that is why for obtaining a strong surface carbon fibre needs to be stacked in several layers changing the direction of the fibres every time. Such fibres join in the same way as glass- plastic fibres by resins. But this process requires more expensive resins of higher quality. Vacuum technologies, heat treatment, compound equipment, for example, autoclave, should be applied for complete use of all advantages of these materials. Carbon is 40 per cent lighter than steel and is 20 per cent lighter than aluminium. Carbon parts are lighter and stronger than glass-fibre-reinforced plastic ones. Since, John Barnard has used carbon fibre in creation of monocoque for McLaren MP4/1 in 1981, this material strongly has come into present-day auto racing sport and gradually is approaching to ordinary cars. The paradox is that that fans of cars liked car carbon for its unusual form not for its outstanding characteristics. Carbon mouldings and cover plates were also brought into fashion thanks to sport cars. But they had a definite function there. It was maximum strength at minimum weight.

Kevlar

    Kevlar became one of the first analogues of the cobweb. Trade mark KEVLAR belongs to the famous American Corporation DuPont. This material was invented by scientists of the Company Stephanie Cwalek and Herbert Blades in 1965. Practically simultaneously with the Americans our kevlar was invented. At the same time TVARON material gained great popularity in Europe. Kevlar benefits are low specific conductivity, high chemical resistance, low thermal shrinkage, high tear and cut resistance. It is heat-resistant. Sport accessories and gears made from kevlar are not only stronger but lighter. This fact can not pass over an effect on the results. Skis, helmets, rackets, foot-gears, clothes, for example clothes for motor-cyclists and swimmers), boats, oars and many other things are produced from it. Kevlar is not only strong but also beautiful material. Pure kevlar has golden colour that is close to colour of a flesh. But it has many other colouring. This fact essentially extends the spectrum of kevlar use in decorative parts production such as door panels and other units of car interior finish. Attempts have been made to combine amazing carbon and kevlar characteristics for a long time. Lately one can often meet carbon-kevlar hybrids. These materials are made from carbon and kevlar cross woven cloth. Such cloth is used in construction of bodies of high-speed boat body shells, monocoques, etc.
