Fiber-reinforced ceramic composite

   
   

Fiber-reinforced ceramic composites contain bundles, tows or hanks of long fibers, wherein the long fiber bundles, tows or hanks are completely surrounded by a short fiber-reinforced matrix, with the long and short fibers having, independently of one another, a mean diameter of from 4 to 12 .mu.m and the long fibers having a mean length of at least 50 mm and the short fibers having a mean length of not more than 40 mm, a process for producing them and their use for producing clutch disks or brake disks.

Os compostos cerâmicos fiber-reinforced contêm pacotes, rebocam ou os hanks de fibras longas, wherein os pacotes longos da fibra, rebocam ou os hanks são cercados completamente por uma matriz fiber-reinforced curta, com as fibras longas e curtas que têm, independentemente de um outra, um diâmetro médio o mu.m de 4 a 12 e as fibras longas que têm um comprimento médio ao menos de 50 milímetros e as fibras curtas que têm um comprimento médio de não mais de 40 milímetros, um processo para produzir os e seu uso para produzir discos da embreagem ou discos de freio.
