Abstract: A process for producing a friction material based on a sheet-like carbon fiber woven fabric for wet-friction elements, such as clutch linings or synchronizing ring linings. The woven fabric of carbon fibers is impregnated with a binder, in particular with a resin, to form a binder-impregnated fiber material. The prepreg is cured for a curing period under a curing temperature which is elevated with respect to the ambient temperature and is pressed mechanically on its surfaces with a pressing mold before the start and/or at least during part of the curing period.

Abstract: A multilayer armor plating material contains a single-piece or multi-piece ceramic or metallic layer which, as seen in the direction of attack, is followed by a rear supporting layer of glass fiber-reinforced plastic (GRP) and/or of carbon fiber-reinforced plastic (CRP). As seen in the direction of attack the ceramic or metallic layer is preceded by a front supporting layer of glass fiber-reinforced plastic (GRP) and/or carbon fiber-reinforced plastic (CRP). As a result, the steel or ceramic layer is optimally embedded in a composite between the front and rear supporting layers and thereby supported. This in particular protects the ceramic or steel material from harmful vibrations caused by repeated impact of projectiles, on account of the higher rigidity of the structure reducing the vibration amplitudes.

Abstract: A fiber-reinforced composite ceramic has a matrix containing SiC and/or Si with a density of greater than 2.5 g/cm3 and an elongation at break of more than 0.3%. A method for fabricating the composite ceramic includes producing a blend containing carbon fibers, carbonizable bonding resin and additional carbon material which has a raw density in a range between 0.7 and 1.8 g/cm3, pressing the blend into a fiber-reinforced green body, carbonizing the green body in order to produce a C/C body, and infiltrating the C/C body with a silicon melt. The fabricated composite ceramic is used as a lining material or armor plating, or for producing reflective surfaces.
