复合材料弯头织物的设计与织造

Manufacture method of the composite elbow

目前制造复合材料弯头主要使用纤维缠绕工艺或手工糊制,而纤维缠绕制品轴向强度不足,手糊制品生产效率低且质量不稳定。介绍一种新型复合材料弯头所使用的环形管状机织物预成型件的成型技术,这种工艺生产的产品具有一次性整体成型、环向强度与轴向强度比优良、规格易于统一、产品质量稳定等优点。

At present the main process of manufacture of composite elbow is filament-winding and handmade shaping. But the product made by filament-winding do not have a enough axial strength, the efficiency of the handmade product is low and the product quality is variable. This thesis introduces a shaping technology of the curved tubing used in a new manufacture process of composite elbow. The products of this process have the advantage of easy-shaping, reasonable ratio of axial strength and encircled strength, specification easy-unifying, stable product quality and so on.
