- Continuous fiber reinforced ceramics (Ceramic matrix composites CMC) are well known for their damage tolerance. Even when critical stresses occur and matrix cracks are induced the fibers are still able to bridge these cracks and prevent catastrophic failure of structural parts. This behavior makes CMC very attractive for application in severe environments at high temperature or corrosive atmosphere. Processing, properties, and application of CMC will be explained with the focus on oxide fiber reinforced oxide matrix systems (OCMC). One of the major processing routes is the lamination of fabrics being impregnated with ceramic slurries. Subsequent shaping, drying, and sintering leads to OCMC components made of so-called “Keramikblech®” (in English “sheet ceramic”). These structures show a versatile design and allow very complex and highly integrated technical solutions. The mechanical properties and the fracture behavior of OCMC will be explained and industrial applications will beContinuous fiber reinforced ceramics (Ceramic matrix composites CMC) are well known for their damage tolerance.
