摘要： A ceramic composite material comprising a crystallized glass as a matrix and ceramic fibers or whiskers as reinforcing materials is disclosed, which is produced by melting a starting glass for the crystallized glass, compositing it with fibers or whiskers of oxide ceramic, then crystallizing the starting glass. This composite material permits to easily incorporate the reinforcing material in a proportion of 50 volume % or more without forming void and, therefore, may possess excellent mechanical strength and fracture toughness. The proportion of the reinforcing material may be increased by applying pressure to a mixture of the starting glass and the reinforcing material upon formation of the composite to thereby force out excess glass. In addition, the ceramic composite material may be efficiently molded into a desired shape by utilizing the property of the starting glass that shows viscous flow upon being heated.
