摘要(Abstract)：

聚对苯二甲酰对苯二胺(PPTA)纤维具有优良的耐热性,通过对进口PPTA短纤维和两种国产PPTA短纤维耐高温性能的研究,探讨在不同温度和停留时间下其力学性能和外观色相的变化情况。结果表明:进口和国产PPTA短纤维耐高温性能相差不大。
Poly(p-phenylene terephalamide)(PPTA) fibers have good heat resistant property.The high temperature resistance and impact resistance of an imported PPTA staple fiber and two local made PPTA staple fibers are investigated,the changes of mechanical properties and appearance under different temperature and residence time are discussed.The results show that there is no big difference in temperature resistance between imported and local made PPTA staple fibers.
