The Mechanics of Progressive Cracking in Ceramic Matrix Composites and Laminates

Abstract

This report provides a brief summary of the principal results obtained in a research program on the mechanics of progressive cracking in ceramic matrix composites and laminates. The report concentrates on (1) progressive transverse matrix cracking in cross-ply laminates, (2) the effect of transverse matrix cracks on the axial response of unidirectional ceramic matrix composites, (3) thermal conductivities of hot pressed SiC/BN composites, (4) microcracking in polycrystalline ceramics. and (5) the effect of matrix cracking and fiber-matrix interfacial debonding on the response of unidirectional ceramic matrix composites.
