摘要

通过高能电子束对超高分子量聚乙烯纤维进行辐射交联，探讨了在不同辐照环境中辐射前后的结构和力学性能的变化。结果表明：凝胶含量和交联度随剂量的增加而增加，溶胀度和交联网链平均分子量随剂量的增加而降低，拉伸强度和断裂伸长率随剂量的增加而降低，拉伸模量随剂量的增加而增加。在空气、真空和乙炔气三种环境中辐照，以乙炔气环境中辐照效果最好，空气中最差。

Abstract

Ultra high molecular weight polyethylene fibers have been crosslinked by electron beam. The structure and mechanical properties of them have been investigated in different irradiation atmospheres. The obtained results show that the gel content and crosslinking density increase with the increase of dose,the swelling ratio and average molecular weight of crosslinked net decrease with the increase of dose,the tensile strength and failure elongation decrease with the increase of dose,the tensile modulus increases with the increase of dose. When the samples are irradiated in air,vaccum and acetylene atmospheres,the effect of irradiation in acetylene atmosphere is best.
