纤维增强热塑性树脂基复合材料界面研究进展

Advance in study of interface of fiber reinforced thermoplastic composite

纤维增强热塑性树脂基复合材料具有优良的耐化学药品性、生产周期短、可二次加工等特点,克服了热固性树脂基复合材料韧性差,断裂延伸率低,易发生早期应力开裂等缺点,可在使用环境苛刻,承载能力要求高的场合得到应用.本文从复合材料界面设计思想入手,评述了纤维/热塑性复合材料界面的最新研究进展,并结合剪滞法对微复合材料的界面测试方法进行了分析讨论.

Fibre reinforced thermoplastic composite has excellent properties in chemical resistant, shorter manufacture cycle, and can be reprocess etc. It can overcome many disadvantages of the thermoset composite, such as, low tenacity, low extension rate and early stress craze and so on. It can be used in harsh environment and in the situation that require higher load capacity. In this paper, the advance in the study of interface of fi- bre/thermoplastic composite was reviewed according to the principle of composite interfacial design, and the advantage and disadvantage of the interfacial testing methods with the Shear-lag model were analyzed.
