摘要/Abstract

摘要： 以50wt%的长玻纤增强尼龙66为原料,通过注塑工艺,制备了复合材料平板和复合材料车轮。测试分析了平板和车轮的玻纤含量、玻纤长度、玻纤取向及其分布,比较了两者纤维分布规律的差异,为复合材料车轮开发提供数据参考。通过车轮径向疲劳试验,研究了复合材料车轮的耐疲劳性能,发现车轮中玻纤长度增加,则车轮的径向疲劳性能得到明显提升,显示了控制纤维长度对于保证长纤维复合材料车轮性能的重要性。

关键词: 长玻纤增强尼龙, 注塑成型, 复合材料车轮, 纤维分布, 径向疲劳试验

Abstract: In this study, polyamide 6,6 (PA66)with 50wt% of long glass fibers (LFT)was processed using injection molding to prepare composite plate and composite wheel. Glass fiber content, glass fiber length and glass fiber orientation in the plate and the wheel were analyzed and compared to provide data for the development of composite wheel. Moreover, through wheel radial fatigue test, it is found that as the length of fiber in wheel increases, radial fatigue performance of the wheel is significantly improved.

Key words: long glass fiber reinforced polyamide, injection molding, composite wheel, fiber distribution, radial fatigue test
