NUMERICAL SIMULATION ON THE EFFECT OF INTERFACE PERMEABILITY ON THE FLOW AND COMPACTION OF THICK COMPOSITE LAMINATES
摘要
Abstract
Based on the effective stress theory and Darcy's flow theory,a multi-field coupled numerical model is developed to simulate the flow and compaction of thick composite laminates.The model is verified by comparing the prediction with the experiment result of a thick unidirectional laminate.A thick cross ply composite laminate model with an interface layer is built,and is used to analyze the effect of the interface permeability on the flow and compaction process of the thick cross ply composite laminate.The calculating results of the thick cross ply composite laminate model are compared with those of the unidirectional laminate model with the same thickness.The results show that,the thick cross ply composite laminate with high interface permeability has the similar flow and compaction process with that of the thick unidirectional laminate.An interface layer with low permeability impedes the flow of the resin in the interior of the thick cross ply composite laminate,and causes a slow increase of fiber content with curing time as compared with that in a unidirectional laminate.The effect of interface layer with low permeability is more obvious in the interior of the thick cross ply composite laminate,and causes a jump in the distribution of fiber content across the interface laver at the end of the flow and compaction process.关键词
