The Research of the Effective Moduli of Particle Reinforced Polymer Composites Based on Interface Debonding

摘要：

This paper is devoted to studying influences of matrix/particle interface debonding and paniculate size in micromechanical predictions of the effective moduli of paniculate reinforced polymer composites (PRPC).The PRPC is regarded as a three-phase composite that includes the matrix,particle and interphase.The formulation for the effective moduli of the interphase is derived by the cohesive zone model,and combined with the Mori-Tanaka method,the micromechanical model for the effective moduli of the PRPC is formulated with emphasis on the effects of the matrix/particle interface,paniculate size and volume fraction.The numerical example shows that the interface debonding,the paniculate size and volume fraction have significant influences on the effective moduli of PRPC.The effective moduli of the PRPC can be used to characterize its damage degree.
