Abstract
A fiber-reinforced composite body containing a first zone made of a ceramic matrix, which predominantly contains silicon carbide and, optionally, silicon and/or carbon and/or compounds thereof, and containing a second zone, which is located on a surface of the ceramic matrix zone and formed form a fiber-reinforced C/SiC ceramic. The fiber length decreases from the exterior of the fiber-reinforced ceramic zone up to the first zone and, optionally, up to one or more other zones that are arranged on the second zone. A method for producing the composite body is characterized by involving a joint infiltration at least of the first zone and of the second zone with liquid silicon and by the carrying out of a siliconization. A composite body of this type can be used, in particular, as armoring in the civil or military sectors.
