ABSTRACT:
A molybdenum disilicide composite comprising refractory metal 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.
