Carbon fibre
reinforced plastic
(CFRP)

Discover fibre composites and their unique properties.

Why you should rely on composites

The targeted combination of carbon fibres and plastic creates an innovative material whose mechanical properties can be specifically adapted to the requirements of the final products.

This technology allows the manufacturing of numerous products that show comparable or better properties than steel and offer significant advantages, especially in lightweight designs.
