Very light, very sturdy and very expensive. The characteristics of carbon fibres can be briefly described in this way. Consequently, their applications were primarily restricted in the past to aircraft and aerospace as well as to sports equipment. In addition, the so-called monocoque and other components of Formula 1 racing cars are produced using a carbon fibre reinforced plastic. Very large CRP components are employed in the wings and hull of aircraft.

After carbonization of the basic organic raw materials into carbon, the fibres are tensioned and thus achieve higher strengths and rigidities. Further processing takes place as rovings. This involves several thousand fibres which are combined into a strand and are then used as reinforcing fibres in woven fabrics. As low filaments (short fibres) they can be added to polymers. Suitably reinforced plastic components can be produced by means of processing equipment such as extruders or injection moulding machines.

To produce carbon fibre reinforced plastics (CRP), several layers of carbon fibres are embedded in a plastic matrix of epoxy resin, thermoplastics or ceramics. Analogue to glass-fibre reinforced plastics (GRP), press or autoclave processes for prepregs or fibre wrappings are used for production. CRP manual laminates are only employed for small scale runs or for individual production.
