SIGRASIC^®

SIGRASIC MF is particularly suitable for applications requiring high wear resistance, high mechanical strength and low weight. In addition to its high thermal conductivity, this material exhibits the typical brittle fracture behavior of a ceramic. A remarkable success is the use of SIGRASIC MF in NASA's "Mission to Jupiter" (JUNO). For this purpose, SIGRASIC MF was used as material for the instrument panels of the satellite.

Ductile materials are obtained by incorporating short carbon fibers into a ceramic matrix. This material is characterized by a pseudo-plastic behavior under mechanical stress. The amount of carbon fibers in the ceramic matrix allows tailoring a wide range of mechanical and physical properties to your requirements. SIGRASIC SF is established in the automotive industry for serial-produced C/SiC brake disks.  

SIGRASIC LF is especially suitable for applications under the highest mechanical stress. By incorporating long or continuous carbon fibers into a ceramic matrix, materials which are more dominated by the fiber properties than by the properties of the ceramic matrix are obtained. This material is characterized by a low density with high elongation at break and high strength. Today, SIGRASIC LF is mainly used in the field of ceramic C/SiC clutch disks for high-performance vehicles.
