Summary

Silicon oxycarbide ceramics coating on carbon single fiber and matrix composite were prepared. The silicon oxycarbide ceramic was derived from hydrolysis and condensation of phenyl group substituted alkoxysilane and the subsequent pyrolysis at 1000–1700°C. In the fractural behavior of the obtained coating or composite, the relationship between heat treatment temperature and the interface of fiber/coating was investigated in terms of fiber efficiency on the tensile strength. In single fiber, the strength and efficiency of fiber heated at 1000°C showed maximum value, and by heating above 1300°C, the reaction between fiber/coating was occurred. On the other hand, the fiber efficiency in fiber bundle heated at 1500°C showed the maximum value. This is due to the effect of fiber pull out through porous matrix, since the reaction of silica and carbon, and the following gas evolution occurred above 1300°C.
