Prediction of textile fabric reinforced composite properties based on Node Interpolation Cell Method

摘要：

in this paper, the mechanical properties of 2-D textile fabric reinforced ceramic matrix composites are predicted by Node Interpolation Cell Method (MCM). NICM is a micromechanics method which employs virtual displacement principle and the Representative Volume Element (RVE) scheme to obtain the relations between the global and local strain. The microstructure of 2-D woven and braided fabric reinforced composite are modeled by two kinds of RVE respectively, then the NICM is used to predict the macroscopic mechanical properties. The fill and warp yarns are mimicked with cubic B-spline and their undulating form are approximated by sinusoid. The effect of porosity on the fiber and matrix is considered as a reduction of elastic module. The connection of microstructure parameters and fiber volume fraction is modeled to investigate the reflection on the mechanical properties. The results predicted by NICM are compared with finite element method. The comparison shows that the NICM is a valid and feasible method for predicting the mechanics properties of 2-D woven and braided fabric reinforced ceramic matrix composites.
