PCT No. PCT/FR93/01297 Sec. 371 Date Jun. 26, 1995 Sec. 102(e) Date Jun. 26, 1995 PCT Filed Dec. 23, 1993 PCT Pub. No. WO94/15888 PCT Pub. Date Jul. 21, 1994The invention relates to the field of structural materials intended for operation under conditions of thermal loading in oxidizing media and useful in working units and equipment for petroleum, chemical, aircraft, and metallurgy industries. The invention makes it possible to obtain a material having increased strength properties, heat resistant to oxidizers at a temperature over 1100 DEG C. and ensuring a desired serviceability of parts without additional protective coatings under these conditions. This is attained due to producing a material being a composition of two interpenetrating skeletons: carbon fibers and silicon carbide disposed all through the material structure; the silicon carbide skeleton being the result of interaction between the matrix carbon and silicon self-propagating from outside. The process if characterized by a relatively short production cycle associated with singly conducted operations.
