Abstract
During Resin transfer molding (RTM) of composites, entrapped air in resin during resin impregnation may remain as voids in the product and depresses the mechanical properties. In this paper, bundle scale void formation in anisotropic plane woven fabric is focused. The effect of anisotropy on void formation is described by simplified model of void formation. Experiments were carried for the validation and good agreement was obtained between the result and the expectation of the analysis model.
