“…All these models can be roughly divided into two types: one-dimensional analytical model typically based on the shear-lag theory 11,12 and the two-dimensional analytical model based on an axi-symmetric analysis. 13,14 The former is simple and it is used extensively. In this study, the comprehensive micro-mechanical model is created based on the shear-lag theory.…”

In this study, two micro-mechanical models for analyzing the stress transferring in single-fiber composites composed of the fiber, the matrix, and the interphase are developed based on the shear-lag theory. The analytical model has taken into account two micro-damage modes, that is, the interficial debonding and the matrix damage, respectively. So, the real distribution of the shear stress at the interface and the axial stress in the fiber in single-fiber composites under loading can be obtained. An approach based on combining the micro-mechanical model with the single-fiber fragmentation test was utilized to determine the property of the interphase. The more accurate and real shear strength of the interphase in single-fiber composites is determined compared with the previous methods.

“…Although small in thickness, interphase can significantly affect the overall mechanical properties of the fiber or particle reinforced composites [2]. For example, a stiff interphase can transfer stress much more rapidly than a soft interphase [3]. In order to form an interphase, Hayes et al [4] applied an epoxy resin with known properties to the surface of untreated reinforcing fibers.…”

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.
