ABSTRACT:
Fiber-reinforced ceramic matrix composite products comprising boron-nitride-coated reinforcing silicon carbide fibers disposed in a substantially non-porous alkaline earth aluminosilicate glass-ceramic matrix are disclosed, the matrix comprising triclinic anorthite (CaO,SrO.Al.sub.2 O.sub.3.2SiO.sub.2) as the principal crystal phase and the products exhibiting unexpectedly good resistance to high-temperature degradation.
