本项研究以商品高性能聚乙烯（HPPE）纤维为对象，采用高能电子束对其进行辐射处理，以达到交联和改进其纤维性能的目的。研究结果表明：高能电子束辐射处理PE可以使其交联，并且交联程度可以通过辐射剂量、环境和预应力等条件变化得到控制；辐射交联后的PE纤维拉伸模量有较明显的提高。本文还对高性能聚乙烯纤维辐射交联前后的结构和性能进行了较详细的探讨，着重研究了辐射剂量、辐射环境对辐射交联的影响；辐射交联对熔点、结晶度、静态和动态力学性能等几方面的影响。
In this study, commercial high-performance polyethylene (HPPE) fibers were treated with high-energy electron beam for radiation treatment to achieve the purpose of crosslinking and improving the fiber properties. The results show that PE can be cross-linked by high energy electron beam irradiation, and the degree of cross-linking can be controlled by the change of radiation dose, environment and prestress. The tensile modulus of PE fiber after radiation cross-linking is more obvious improve. In this paper, the structure and properties of high-performance polyethylene fiber before and after radiation crosslinking were discussed in detail. The effects of radiation dose and radiation environment on the radiation crosslinking were studied. The effects of radiation crosslinking on the melting point, crystallinity, static and dynamic Mechanical properties and other aspects of the impact.
