1.概述 缠绕法制造复合材料圆管有连续缠绕和定长缠绕两种工艺方法。连续缠绕法是由与芯轴成β_1、β_2角单走向的两束浸胶纤维缠绕、快速固化而成。定长缠绕法是往返式的螺旋缠绕层和环向缠绕层的组合,这种管子其力学性能是轴对称的,在内压作用下不会产生“扭曲”或“弯曲”变形,能延缓树脂基体及其界面的开裂,具有比连续缠绕的管子更好的抗渗漏能力。 定长管的缠绕在工艺上、设备设计上有所谓两端回程时的滑线问题。要使纱线缠绕到两端不滑线,就要借助于芯模表面或缠绕层表面的摩擦力及合理的丝嘴回程运动控制。首先要 1. Overview Winding method of manufacturing composite pipe with continuous winding and fixed-length winding two processes. Continuous winding method is composed of β23, β_2 angle with the mandrel, a single direction of the two dipped fiber winding, rapid curing. The fixed-length winding method is a combination of reciprocating spiral wound layers and toroidal wound layers. The mechanical properties of such tubes are axisymmetric, and will not cause “distortion” or “bending” deformation under internal pressure, Cracking of the substrate and its interface provides better resistance to leakage than continuous wound tubes. Fixed-length tube winding in the process, equipment design has the so-called two-end return slip problem. To make the yarn wrapped around the non-slip line, it is necessary to use the core surface or the winding surface friction and reasonable nozzle back movement control. First of all
