摘要： The present invention discloses a method of resin transfer molding which comprises superposing a bagging film on a layer of reinforcing fibers laid on a mold, airtightly bonding the periphery of the bagging film to the mold, evacuating the space between the bagging film and the mold, injecting a resin into the space between the bagging film and the mold to thereby impregnate the resin into the reinforcing fibers, and curing the resin, characterized in that resin injection passages and resin discharge passages are alternately formed outside the reinforcing fiber layer along a surface of the reinforcing fiber layer and the resin is injected into the resin injection passages to allow the resin injected to move to the resin discharge passages via the reinforcing fiber layer and thereby impregnate the resin into the reinforcing fiber layer.
摘要翻译：本发明公开了一种树脂传递模塑方法，其包括将装袋膜叠加在模具上的增强纤维层上，将装袋膜的周边气密地粘合到模具上，抽空袋装和模具之间的空间，将树脂注射到装袋膜和模具之间的空间中，从而将树脂浸渍到增强纤维中，并使树脂固化，其特征在于树脂注入通道和树脂排出通道沿着增强纤维层的表面交替地形成在增强纤维层的外侧将增强纤维层和树脂注入到树脂注入通道中，以使注入的树脂经由增强纤维层移动到树脂排出通道，从而将树脂浸渍到增强纤维层中。
