Monolithic silicon carbide and silicon nitride and a Nicalon© fiber-reinforced silicon carbide composite were subjected to severe thermal shock conditions via impingement of a hydrogen/oxygen flame. Surface heating rates of 1000°-2500°C/s were generated. The performance of the monolithic reference materials is compared and contrasted with the significantly greater thermal shock resistance of the composite. Ultrasonic and radiographic NDE techniques were used to evaluate integrity of the composite subsequent to thermal shock. Tensile tests were performed to determine the residual tensile strength and modulus. Physical property changes are discussed as a function of number and severity of thermal shock cycles.
