Abstract

image

The 2D-SiC/SiC composite has higher ability to resist the thermal shock in 0° direction with higher fiber volume fraction, compared with 90° specimen. The greater degradation in the mechanical properties for the 90° specimen suggests more serious damage in the 90° fiber bundles. The damage caused by the thermal shock involves matrix cracking, debonding, and oxidization of fiber/matrix interface.
