FIELD: composite materials. SUBSTANCE: frame is made by way of assembling carbon-fiber rods into cylindrical bundle which is further reinforced with carbon fibers. Frame is then heated to 900-950 C by directly passing current in natural gas medium, and kept at that temperature for no more than 24 h. Tested for oxidation resistance in air at 1200 C, material revealed considerable increase in heat resistance, weight loss for 6 h being 27-28%. EFFECT: increased oxidation and heat resistance. 2 cl, 1 tbl
