往复式纤维缠绕工艺(属于定长法)：在这种工艺方法中，浸胶槽随转动的芯模作往复运动，长纤维玻璃丝以一定的斜角相对于芯模轴辅放，辅角(即缠绕角)受浸胶槽的移动速度和芯模转速之比控制，浸胶槽的平移运动由计算机化的机-电控制。缠绕层数逐渐增加，达到设计的壁厚为止。缠绕完成后，使制品中的树脂基本固化。固化后，从玻璃钢管中脱出芯模。
Reciprocating filament winding process (belongs to fixed length method): In this process, the dipping trough moves reciprocating with the rotating mandrel, the long fiberglass filament is placed with a certain pajiahulu.07858.net fanghuomen.07858.net suliaojixie.71ix.combaowenban.71ix.comdiguandai.07858.netzhoucheng.71ix.comoblique angle relative to the mandrel axis, the auxiliary angle (i.e. the winding angle) is controlled by the ratio of the moving speed of the dipping trough to the rotating speed of the mandrel, and the translation motion of the dipping trough is controlled by computerized machine-electricity. The number of winding layers increases gradually until the designed wall thickness is reached. After winding, the resin in the product is basically cured. After curing, the core die is removed from the FRP pipe.
