Summary

Critical parameters for high-performance fiber-reinforced ceramic-matrix composites are the matrix microcracking stress, the UTS, and work of fracture. These parameters are determined by interface microstructure in addition to the properties of individual phases. The objective of this program has been to study the compatibility of SiC fibers (principally Tyranno) with various silicate matrices prepared via conventional glass melting or via the sol-gel route, followed by hot-pressing.

Analytical electron microscopy has been used to define interface structure and matrix crystallization in systems with borosilicate (Pyrex), cordierite (MAS), and celsian (BAS) matrix compositions under varied processing conditions. The stability of interface and phase structure during high-temperature treatment in different atmospheres has been studied in selected systems. Some comparisons have been made with stoichiometric SiC whiskers in similar silicate matrices.
