摘要(Abstract):

选取了不同细度的超高相对分子质量聚乙烯(UHMWPE)纤维,使用二维广角X射线衍射仪表征纤维结构,利用差示扫描量热仪、万能试验机、卷曲弹性仪以及摩擦因数仪对纤维的热学性能、力学性能以及可纺性能进行测试与分析。结果表明:细度越小的纤维有着越高的结晶程度,同时也赋予其更优异的力学及热学性能;而细度较大的纤维具备更好的韧性,能够提高纤维的可纺性。
In this paper, ultra high molecular weight polyethylene(UHMWPE) fibers with different fineness were selected, and the fibers structure were characterized by two-dimensional wideangle XRD the thermal properties, mechanical properties and spinnability of the fibers were measured and analyzed by differential scanning calorimetry, universal testing machine, crimp elasticity tester and friction coefficient tester. The results showed that the smaller fineness of the fibers were with the higher degree of crystallization which gave fibers superior mechanical and thermal properties. On the other hand, the higher fineness of the fibers had better toughness which could improve the spinnability of the fibers.
