摘要/Abstract

摘要： 本文对聚醚醚酮（PEEK）纤维及其织物的应用性能进行了广泛研究。结果表明，所得PEEK纤维的断裂强度为6.6 cN/dtex，断裂伸长率为12.6 %，回潮率为2.19 %，其织物平均耐磨次数为6785次；经过270 ℃下50天的热老化，PEEK纤维变黄发硬，尺寸变化率为-9.9 %，但纤维和织物的断裂强力能保持80 %左右；通过IR、XRD和DSC等仪器分析发现，PEEK纤维老化前后力学性能、颜色等的改变，主要是由链段的解取向及少量的断裂、支化、交联引起的，结晶度大幅增加和结晶更加完善是其强力仍能保持在较高水平的原因。

Abstract: The properties of PEEK fiber and its fabric were widely studied. The results showed that the breaking strength of drawn PEEK fiber was up to 6.6 cN/dtex, the breaking elongation percentage was 12.6 %. The moisture content of PEEK fiber was 2.19 %, and the average abrasion resistance of PEEK fabric was 6785 times. After a heat aging at 270 ℃ for 50 days, PEEK fibers yellowed and became brittle, the dimensional change of PEEK fabric was -9.9 %, but the breaking strength retained about 80%. Through IR, XRD and DSC analysis, it was found that the change of mechanical performance and color of PEEK fiber after heat aging were due to the relaxation of segments and the breaks or branched of few chains. And the increasing and perfecting of crystalline were the main reasons for the high conservation rate on the strength of PEEK fiber.
