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.
