Recent Research Activities for Continuous SiC Fiber Reinforced Ceramic Matrix Composites in Japan

In this article, the present activities regarding research and development of continuous SiC fiber reinforced ceramic matrix composites (CFCC) in Japan are reviewed. The key technologies in SiC fiber composites are interphase between fiber and matrix and its oxidation resistance. To improve oxidation resistance ofinterphase, various kinds of technologies such as environment barrier coating, high dense matrix, unti-oxidation matrix, multi-layered intephase have been developed. It is suggested that high performance, affordable processing cost, and excellent reliability will be important factors to be in practical use of CMCs in future.
