ABSTRACT:
A molybdenum disilicide composite comprising ceramic reinforcing fibers and sufficient particulate silicon carbide, silicon nitride, boron nitride or silica to modify the coefficient of thermal expansion of the matrix to match that of the fiber is found to have improved high temperature strength, creep resistance, toughness, and resistance to matrix cracking during thermal cycling.
