| Abstract: | Poly（p-phenylene terephalamide） （PPTA） fibers have good heat resistant property. The high tem- perature resistance and impact resistance of an imported PPTA ＂staple fiber and two local made PPTA sta- ple fibers are investigated, the changes of mechanical properties and appearance under different tempera- ture and residence time are discussed. The results show that there is no big difference in temperature re- sistance between imported and local made PPTA staple fibers. |
