摘要
本工作以平面Ｃｈａｒｐｙ冲击、缺口与非缺口Ｃｈａｒｐｙ冲击全面地研究了本实验所制备的超高模量聚乙烯（ＵＨＭＰＥ）纤维－碳纤维混杂增强环氧复合材料的冲击性能。同时根据试样在冲击过程中的载荷－时间曲线以及试样在冲击破坏后的形貌对该类混杂复合材料的冲击破坏过程与冲击破坏模式进行了分析。结果表明，将ＵＨＭＰＥ纤维与碳纤维相混杂，复合材料的冲击性能呈现出明显的正混杂效应。
The impact behavior of ultra high modulus polyethylene (UHMPE) fibre/carbon fibre/epoxy hybrid composites was investigated by notched and unnotched Charpy impact tests. The results showed that hybridizing carbon fibres with UHMPE fibres led to an increase in the impact strength of the hybrid composites. Based on the load time curves of the specimens during impact and the morphology of the specimens after impact, the failure modes of the hybrid composites were analyzed in detail.
