含孔隙碳纤维/环氧树脂层合板力学性能模拟
Simulation on mechanical properties of carbon fiber reinforced epoxy laminates with voids
摘要
Abstract
The study investigated the influence of the porosity on the tensile strength and compressive strength of the carbon fiber fabric reinforced epoxy composites laminates. The tensile strength and compressive strength test on the carbon fiber reinforced polymer (CFRP) laminates with porosity of 0. 33% , 0. 71% and 1. 50% were conducted and simulated by a finite element analysis model. The experiment results show that the tensile strength and compressive strength decrease as the void contents increase. The failure criterion of static mechanical strength of the fabric fiber reinforced composites is provided. Basic strength parameters of composites were used to evaluate the mechanical properties of CFRP laminates with different porosities. A finite element analysis model was established by using ABAQUS software, combined with a model of sudden stiffness degradation. The tensile strength and compressive strength of the fabric carbon fiber reinforced the epoxy composites laminates were accurately simulated.关键词
