ABSTRACT The interest in natural fibre composites as load-bearing elements has increased strongly in recent years. As natural fibres offer good biodegradability, strong reinforcement and low production costs, some industry sectors have started to substitute conventionally used materials. One excellent example for natural reinforcements is curaua fibres. Regardless, the use of natural fibres in prepregs is still in its infancy, the manufacturing parameters need to be analysed. For this reason, the amount of curing agent, fibre treatment and filler amount of curaua fibre/epoxy prepreg are tested in this research. Thermogravimetric analysis and differential scanning calorimetry techniques were used for analysis. The compared material properties were the degree of crosslinking and the degradation stability. The results were analysed with a statistical comparison method (a factorial experimental design), which revealed a complex relationship of the influencing parameters on the thermal properties of the prepregs.

固化剂、处理和纤维含量对curaua/环氧树脂预浸料热性能的影响

摘要 近年来，人们对天然纤维复合材料作为承重元件的兴趣大大增加。由于天然纤维具有良好的生物降解性、强增强性和低生产成本，一些工业部门已经开始替代传统使用的材料。天然增强材料的一个很好的例子是curaua 纤维。无论如何，天然纤维在预浸料中的使用仍处于起步阶段，需要分析制造参数。为此，本研究测试了固化剂用量、纤维处理量和curaua纤维/环氧树脂预浸料的填料用量。使用热重分析和差示扫描量热技术进行分析。比较的材料特性是交联度和降解稳定性。
