摘　　要：研究了导流介质尺寸对真空辅助树脂传递模塑（VARTM）工艺中树脂流动行为的影响，以及对复合材料制品中纤维分布和空隙率的影响。结果表明，随着导流介质尺寸的增加，树脂在增强体中的流动速度加快，并呈现指数加速趋势；制品中纤维体积含量呈现先减少后增大的趋势，并且以导流介质边界为纤维体积含量高低的分界线；复合材料制品的空隙率范围在3．86％19．92％，空隙率呈现先增大后减小再加速增大的趋势。Effects of the size of infusion media on resin flow behavior, fiber volume fraction distribution and void content in vacuum assisted resin transfer molding（VARTM） were studied.The results showed that with the increase of infusion media size, the resin flow rate increased exponentially ; the fiber volume fraction showed a tendency to increase after the first decrease, and the infusion media boundary was just the high and low fiber volume fraction line ; the void content increased first and then decreased and increased tremendously at last, varied from 3.86% to 19.92%.
