ABSTRACT:
Fiber-reinforced glass-ceramic matrix composites exhibiting substantially increased resistance to stress failure above the microcrack point in a hot oxidizing environment are provided by introducing into the composite a matrix additive consisting of a stable, refractory, chemically compatible glass. The glass is disposed as an intergranular glass phase in the crystalline aluminosilicate glass-ceramic matrix of the composite, which may further comprise a whisker addition to the matrix to increase the high-temperature viscosity of the intergranular glass.
