ABSTRACT:
Ceramic matrix composite articles comprising a matrix phase composed of a silicate glass or glass-ceramic and a matrix reinforcement material disposed within the matrix comprising carbon (e.g., graphite) fibers are described, wherein the fibers are provided with a protective boron nitride surface coating. The mechanical properties of the composites at high temperatures are substantially improved.
