Abstract
During Resin transfer molding (RTM) process for manufacturing composites, entrapped air may remain as void in a part to bring significant decrease of the mechanical properties. In the past, it has presented that amount of the void formation depends on velocity of resin flow. However, in the case that an anisotropic fabric is applied, directions of the resin flow may also affect on the void formation. In this paper, the effect of anisotropy of fiber on void generation was examined analytically and experimentally. Finally, good agreement was obtained between results of them.
