R-Curve Behavior for Silicon Carbide Whisker Reinforced Aluminum Oxide Composites

Abstract

As a structural material, ceramic matrix composites have received a great deal of interest in recent years. The attention has focused primarily on the increase in mechanical reliability of the composites as compared to that of monolithic ceramics, which are extremely brittle materials. To reduce the brittle nature of these monolithic ceramics in environments where the are used for their mechanical reliability, research efforts have concentrated in the domain of ceramic matrix composites. The basic principle is that to prevent catastrophic crack propagation, other phases must be incorporated into the ceramic matrix that can generate obstacles needed to dissipate the crack energy.
