摘要
高分子材料的自增强与外增强不同,它是充分利用材料本身的潜力,改变其内部的聚态结构,形成内在的增强相,达到增强的目的。由于自增强材料的增强相和基体相具有完全相同的分子结构,因此增强相与基体相之间不存在外增强材料中普遍存在的界面问题,表现出整体结构的优异的比强度和比刚度,而且具有较高的冲击韧性和耐化学稳定性。
The mechanical property and microscopic morophology of self-reinforced HDPE were investigated. The tensile strength and modulus of self-reinforced HDPE, compared with those of normal HDPE, were enhanced appreciably. The morphological structure was changed as a result of self-reinforcement. The shish-kebab and the fibrous structure in self-reinforced HDPE were given credit for its excellent property.
