SILICON CARBIDE FIBER REINFORCED CARBON COMPOSITES ABSTRACT OF THE INVENTION The present invention provides an article comprising a plurality of silicon carbide containing fibers in an inhibited carbon matrix. The present invention also provides a shaped material for structural applications comprising a plurality of silicon carbide containing fibers in a carbon matrix formed by impregnating said fibers with an organic resin and staging to form a prepreg, shaping and curing said prepreg to form a laminate, carbonizing said shaped laminate to form a carbonized part, and densifying said carbonized part by chemical vapor infiltration to form a component. The present invention further provides a process for producing a reinforced component comprising: (a) impregnating a plurality of silicon carbide fibers with an oxidation inhibiting filler- containing organic resin, (b) staging said impregnated fibers to partially cure said resin to form a prepreg, (c) shaping and curing said prepreg to form a laminate, (d) converting said resin in the laminate to carbon to form a carbonized part, (e) densifying said carbonized part by chemical vapor infiltration to form the component.
