PROBLEM TO BE SOLVED: To provide a composite material having high oxidation resistance and durable at high temperature. SOLUTION: The composition material includes: a fibrous structure having a surface and partially impregnated with an interface material, a first ceramic material, a ceramic mixture and metal alloy; and a coating at least partially disposed on the surface of the fibrous structure. In one aspect, the coating contains further glass. In another aspect, the first ceramic material contains silicon carbide. In further another aspect, the ceramic mixture contains silicon carbide and boron carbide. In a different aspect, the metal alloy contains at least one of silicon and silicon alloy. In further different aspect, the first ceramic coating contains at least one of boron carbide or boron carbide containing much carbon. COPYRIGHT: (C)2010,JPO&INPIT |
