Do your applications require a particularly ductile behavior or damage tolerance in addition to high hardness, low thermal expansion and high chemical resistance at high temperatures? If so, we can find the right solution for you! Our fiber reinforced ceramics combine the properties of carbon fiber with a ceramic silicon carbide (SiC) matrix. Depending on the type and amount of fibers, the mechanical properties can be adapted to your needs. To adjust the mechanical properties, milled fibres, short fibres and long fibres can be used. Even complex component geometries can be realized by near-net-shape production.

Our fiber reinforced ceramics combine the unique properties of carbon fiber with a silicon carbide matrix. This makes it an ideal material for high performance applications. Find out more about the wide range of applications below.
The use of fiber reinforced ceramics in NASA's "Mission to Jupiter" (JUNO) is a remarkable success. For the instrument panels of the satellite, which are manufactured with high precision, it is important that their shape remains stable even under conditions in space. This can be ensured by the low thermal expansion and the high stiffness of the fiber reinforced ceramic. Other advantages of the material can be found in its high mechanical strength, low weight and excellent thermal conductivity.
A key criterion for brake discs is their responsiveness. Compared to conventional brake discs, the friction coefficient of brake discs made of fiber reinforced ceramics is several times higher, which leads to a significant reduction in stopping distance. In addition, they are characterized by a lower wear, a higher temperature resistance and on top of this it is a lightweight solution!
The demands on clutch discs are especially high in motor sports. Here our customers trust in the unique material properties of fiber reinforced ceramics. Compared to clutch discs made of other materials e.g. metal-plastic composites, discs made of fiber reinforced ceramics offer significantly higher friction coefficients and lower wear at a significantly lower weight.
Fiber reinforced ceramics are manufactured by infiltrating porous carbon fiber reinforced carbon components with liquid silicon. The material properties can be customized to your application by the amount and type of carbon fibers (milled fibers, short or long fibers) which are implemented into the ceramic SiC matrix.
