Abstract
Vacuum assisted resin transfer molding (VaRTM) is a manufacturing method of fiber reinforced polymer composites, and has the advantage of a low-cost because of unnecessary of autoclave. In anisotropic fabric, direction of resin flow may affect to void formation since the fiber structure differs from the direction against the fiber orientations. In this work, the mechanism of void formation in a plane woven anisotropic fabric is investigated. We constructed analytical model of void formation between fiber bundles m plane woven fabric, it was shown that anisotropy of fiber affects the relationship between impregnation velocity and void content.
