本论文主要采用热压工艺制备了PSAf/PTFE复合材料。对所制备的复合材料,采用TGA、DSC、XRD、FTIR、TFSEM等测试方法研究了PSA纤维对复合材料的力学性能、热稳定性、结构与微观形貌等的影响。结果表明,PSA纤维的加入提高了复合材料的力学性能,复合材料具有优异的热稳定性能。适量的PSA纤维可以较好的分散在PTFE基体中,PSA纤维与PTFE基体的界面结合较好,同时存在物理与化学结合。

In this thesis, PSAf / PTFE composites were prepared by hot pressing process. The effects of PSA fibers on the mechanical properties, thermal stability, structure and microstructure of the composites were studied by TGA, DSC, XRD, FTIR and TFSEM. The results show that the addition of PSA fiber improves the mechanical properties of the composites, and the composites have excellent thermal stability. An appropriate amount of PSA fibers can be well dispersed in the PTFE matrix, the interface between the PSA fibers and the PTFE matrix bonds well, and physical and chemical bonding exists at the same time.
