Abstract

Fiber-reinforced ceramic composites are obtained by the use of a prepreg comprising sized carbon fibers bonded together with a matrix composition which comprises about 25-60% by weight of a polysilazane and about 75-40% by weight of at least two ceramic powders selected from silicon metal, silicon carbide and silicon boride powders.
