Discontinuous silicon carbide fiber reinforced glass composites are disclosed having high strength, fracture toughness, and oxidative stability, even in high temperature oxidative environments. Disclosed composites include silicon carbide fiber reinforced borosilicate glass, high silica content glass, and aluminosilicate glass. Flexural strengths in excess of 20,000 psi (138 MPa) at temperatures in excess of 500°C. are attained with such composites.

A silicon carbide fiber reinforced glass composite consisting essentially of about 15% to about 50% by volume high strength and high modulus of elasticity discontinuous silicon carbide fibers laid up in substantially in-plane random orientation in a glass matrix selected from the group consisting of borosilicate glass, high silica content glass, aluminosilicate glass, and mixtures thereof, so as to produce strength and fracture toughness properties greater than that of the glass matrix at temperatures in excess of 300°C. in an oxidizing environment.
