Summary

The behavior of SiC/BMAS composites was investigated under tensile and flexural loading. Crack development was followed microscopically to better understand the deformation process. Comparison of data in tension us flexure indicates that a properly designed and instrumented flexural test may be used to help guide materials development and to screen composite systems. A unique aspect of ceramic composite behavior, termed transverse strain reversal, is reported for the first time. The occurrence of this phenomenon is believed due to the formation of axial matrix micro-cracks and to fiber-matrix debonding.
