Summary

Mechanical properties of ceramics can be improved substantially by reinforcement with strong fibers. In situ observations during mechanical loading reveal that the reinforcements inhibit cracking by forming bridges between crack surfaces. Fracture mechanics analyses have been developed to evaluate the influence of the bridging ligaments and to relate macroscopic properties such as residual stresses, fiber-matrix interface properties, and individual properties of the fibers and matrix. Recent advances in this topic will be reviewed.
