<P>PROBLEM TO BE SOLVED: To provide a boron carbide silicon carbide silicon composite material which exhibits excellent grindability and high bending strength, while having high specific rigidity of boron carbide, and thus enables formation of a structural member having reduced thickness and weight. <P>SOLUTION: In a composite material mainly composed of boron carbide, silicon carbide and silicon. The boron carbide particles in the composite material have an average particle diameter of not less than 10 μm but not more than 30 μm. <P>COPYRIGHT: (C)2010,JPO&INPIT |
