| 摘 要： | <正> 由于超高模量聚乙烯(Ultra-High Modulus Polyethylene,简称UHMPE)纤维可望作绳索和复合材料等工程材料而在工程上获得广泛应用,面临的一个重要任务就是设法尽可能地改善其力学性能,已有几篇研究论文报道了不同拉伸比,不同分子量和γ辐射对UHMPE结构和性能的影响,这些方法都在不同程度上改善了纤维的性能。本实验则研究了各种不同剂量的电子辐射对UHMPE高弹性性能及结构的影响。至于电

| Abstract: | The effects of electron irradiation on the rubber elasticity of electron-irradiatedn-polyethylene filaments were studied. The results showed that the dose of gelation is about 2.4 ~ 3.0 Mrad.The experiments also infered that the average molecular weight between entanglements in the linear polyethylene with Mn= 28000 is about 15000. |
