摘　　要：通过使用不同的加工成型条件制备结晶程度不同的PEEK树脂材料,对其在低温、室温和高温下的机械性能进行测试,结果证明结晶程度对树脂的机械性能具有很大的影响.DMA测试的结果表明,不同的加工条件导致的分子链间高级结构的不同显著的影响材料的粘弹性行为.TMA测试结果说明,热历史对PEEK的尺寸稳定性有显著的影响.PEEK resins with various degrees of crystallization were prepared by controlling processing conditions. Mechanical properties,which were evaluated at subzero temperature, room temperature and elevated temperature, were significantly affected by the crystallization conditions. DMA tests displayed a strong dependence of the materials＇viscoelastic properties on the macromolecular higher structure which was induced by various processing parameters. TMA results demonstrated that dimensional stabilities of PEEK were influenced by the thermal history.
