Summary

The evolution of damage in continuous fiber-reinforced oxide\oxide matrix composites was investigated at ambient temperature using an infra-red camera and a servohydraulic testing machine. The material used in this study consisted of 12 layers of un-coated fabric of NextelTM 720 (either 0\90 or ±45° fiber orientation with respect to the loading direction) and an aluminosilicate matrix. Straight-sided specimens 100 mm long and 12.5 mm wide with center holes were tested for a\w between 0.1 and 0.4. It was possible to record the onset of “necking”, the propagation of cracks in the matrix, and the rotation of fiber bundles during matrix crack growth. These processes were recorded using a fast-speed digital image recorder\analyzer, and the sequence of events is presented.
