热残余应力对C/SiC复合材料界面剪切强度影响的有限元分析
Finite Element Simulation of Interface Shear Strength of C/SiC Composites with Thermal Residual Stress
摘要
Abstract
Considering the influence of residual stress on interface shear strength in the preparation process of C/SiC composite material,a two-dimensional axisymmetric model of single fiber push-out was established to study the interface shear strength of the C/SiC composites by finite element method.The interface shear stress and its related influencing factors in the push-out process were analyzed in the mesoscopic mechanical level.It was analyzed that the residual stress can cause damage to the interface,reduce the interface debonding load.The interface capacity was positively correlated with the thermal expansion coefficient,and negatively correlated with curing temperature.关键词
