近年来,玻璃纤维增强热塑性塑料的复合结构材料,在工艺和结构上有了新的改进,品种和数量逐年增加,使用范围不断扩大。由于这种材料的性能优良,因此深受用户欢迎。本文主要介绍三种新工艺方法及其产品的性能和用途。这三种工艺:(一)EPF工艺——先由挤压机挤压出热塑性塑料管作为芯子,经冷却烘干后,在这个芯子上挤拉成型热固性的FRP,用以增强轴向强度;然后在这层挤拉的FRP层外面缠绕成型
In recent years, glass fiber reinforced thermoplastics composite structural materials, in the process and structure has been a new improvement, the variety and quantity increased year by year, the use of expanding. Because of the excellent performance of this material, so popular with users. This article describes the three new processes and their products performance and use. The three processes: (a) EPF process - the first extruder extruded thermoplastic tube as a core, after cooling and drying, in this core pultrusion molding thermosetting FRP, to enhance the axial Strength; and then wound on this layer of pultruded FRP layer wound shape
