Title: Matrix cracking in crossply ceramic matrix composites under quasi-static and cyclic loading

Abstract

Experimental data are presented for the development of 90[degree] ply and 0[degree] ply cracking in two crossply silicon carbide fiber/calcium aluminosilicate matrix laminates under quasi-static loading. Under mechanical fatigue loading it is found that there is an increase in ply crack densities and a corresponding laminate stiffness reduction with cycling. Possible mechanisms to account for these observations are proposed. A model is presented which describes the stress/strain behavior as a function of crack densities based on assumptions of frictional load transfer between fiber and matrix in the longitudinal plies and elastic bonding between the longitudinal and transverse plies.
