ABSTRACT:
A method is provided for producing a fiber-reinforced material which is composed, at least in a region of a surface layer, of a ceramic composite and has carbon-containing fibers reaction-bonded to a matrix containing the elements Si and C. In particular a method of producing fiber-reinforced silicon carbide is provided in which a structure of a matrix contains cracks and/or pores, at least at ambient temperature, because of a high thermal expansion coefficient compared with that of the fibers. Metals are selectively electrodeposited in the open pores and cracks of the matrix and, in particular, in a region of the electrically conductive reinforcing fibers. As a result, the open pores and cracks are filled and, in addition, metallic top layers are optionally formed that are firmly keyed to the ceramic composite and that may serve as an interlayer for glass top layers or ceramic top layers. A fiber-reinforced composite material, as well as moldings, in particular brake discs, brake linings or clutch plates, composed of such a composite material, are also provided.
