PPTA纤维的制备及其结构和性能研究

Fabrication and structure and performance research of poly(p-phenylene terephthalamide)fiber

聚对苯二甲酰对苯二胺纤维(PPTA纤维)是最重要的芳纶纤维,为重要的结构材料。通过对PPTA纤维国内外进展及制备工艺的研究,详细讨论了PPTA纤维结构与性能之间的相关性。基于不同研究人员得到的结果,重点对PPTA纤维内部微结构进行了深入分析,同时还分析了微孔存在的证据及微孔对力学性能的影响。

Poly（p-phenylene terephthalamide）fiber is one of the most important aramid fibers and the structural materials.The fabrication process and the progress of the PPTA fiber were reviewed.The relationship between microstructure and its performance was also discussed in detail,so it was the issue in the characterization of the microvoids and potential solution.
