Carbon fibre

Carbon fibres are industrially produced fibres that have high specific stiffness and tensile strength. They are converted from raw materials containing carbon (normally polyacrylonitrile, also pitch for high-modulus fibres) into a special carbon structure by means of pyrolysis.

To ensure good wetting of the fibre surface on contact with liquid resin and a good connection between the hardened matrix and the fibre surface, the carbon fibre is given a finish (sizing) during the production process.

Thanks to high mechanical characteristics, carbon fibres can be used to produce light and high-quality composite components and materials. Carbon fibres can also be used to produce composite materials with almost neutral thermal expansion behaviour. Carbon fibres also conduct electricity and are transparent to X-ray.
