Interphase effect on the interfacial debonding behavior in short-fiber-reinforced rubber composites

Abstract

The interfacial debonding behavior of short-fiber-reinforced composites (SFRC) can be an interesting subject for many investigators. In this paper, the effects of interphase properties on the interfacial debonding behavior of SFRC are investigated. Based on the shear lag model, the initial strain of the interfacial debonding is derived. The results of analytical model show that the interfacial debonding behavior strongly depends on the interphase elastic modulus and thickness and suitable interphase parameters could prevent the onset of the interfacial debonding.
