CERAMIC-FORMING COMPOSITE, CERAMIC COMPOSITE MATERIAL BASED ON THEREOF AND METHOD OF PRODUCING Russian patent published in 2002 - IPC

FIELD: ceramic materials. SUBSTANCE: invention relates to a field of production of ceramic-forming composites and ceramic composite materials based on high-module ceramic filling agents. Invention relates to the development of ceramic-forming composite solidifying in oxygen-free medium without hardening initiating agents with high yield of ceramic residue and providing the formation of interface fiber-matrix without application of intermediate protective layers on reinforcing filling agent; ceramic composite material based on this composition with high strength indices; method of producing said material excluding stages of repeated impregnation, solidification and pyrolysis. Invention proposes a ceramic-forming composite comprising, mas. pts. : polycarbosilane, 100; oligoetheracrylate or polyorganosilazane, 20-50; solvent, 180-225; ceramic composite material based on ceramic-forming composition comprising of polycarbosilane, oligoetheracrylate or polyorganosilazane and solvent, refractory powder-like and reinforcing fibrous filling agents in the following ratio of components, mas.pts.: ceramic-forming composition, 100; refractory powder-like filling agent, 1-10; reinforcing fibrous filling agent, 20-40. Method of producing ceramic composite material involves preparing a suspension by mixing ceramic-forming composite with refractory powder-like filling agent, application of suspension on reinforcing fibrous filling agent, formation and pyrolysis of preceramic material in inert medium or under vacuum. The use of proposed invention ensures to obtain ceramic composite materials with high level of strength indices and heat resistance without additional stages of impregnation, solidification and pyrolysis. EFFECT: improved method of producing, simplified process, decreased time of producing. 6 cl, 3 tbl, 1 ex
