摘要

Inelastic response of ceramic matrix woven 2.5 -D C/SiC composites have been analyzed using quasi-static test data. The changes in composite stiffness properties (elastic modulus, in-plane and out-of-plane Poisson's ratio) are determined experimentally. The increase of residual strains with the applied stress is analyzed and described by simple functions. Micromechanical damage mechanisms observed and quantified using optical microscopy.
