FIBRE-REINFORCED CERAMIC BODY, brake disc comprising such body AND METHOD FOR PRODUCING SAME

The invention relates to a fiber-reinforced ceramic body and a method for producing same. The ceramic body consists of a core and a boundary layer (93, 94) which is joined to the core and has at least one outer surface (96, 97) which can preferably be subjected to tribological stress. The core consi...

Zusammenfassung:The invention relates to a fiber-reinforced ceramic body and a method for producing same. The ceramic body consists of a core and a boundary layer (93, 94) which is joined to the core and has at least one outer surface (96, 97) which can preferably be subjected to tribological stress. The core consists of one or more layers (92) of which at least one is reinforced with long fibers. The boundary layer (93, 94) is reinforced with short fibers. The fibers are preferably reaction-bonded in a matrix by melt infiltration and are made of high-temperature resistant fibers with covalent bonds on the basis of silicon, carbon, boron or nitrogen.
