Abstract

A fiber toughening model of fiber-reinforced ceramic matrix composites is presented. The constitutive equation is obtained through micromechanical considerations based on two kinds of fiber toughening mechanisms, crack bridging and fiber pullout. The calculated results show that two different zones in the R-curve and Load/displacement curve exhibit notable nonlinear behavior. Calculated toughness of 50 vol%SiC_f/LAS composites is in good agreement with experimental results.
