Abstract:

In order to further improve the heat resistance of polyimide fibers, the poly (amic acid) solution from fully-rigid dianhydrides and diamines was synthesized. The polyimide fibers were prepared through dry spinning technology for improved mechanical properties, followed by thermal cyclization and drawing progress. The thermal and mechanical properties of the fibers were analyzed. The results show that the thermal stability of polyimide fibers is superior, mainly attributing to the high density of the benzene ring in the internal structure of the dianhydride and diamine. Under nitrogen atmosphere, the 5% weight loss temperature and the maximum decomposition temperature of polyimide fiber reach 600 ℃ and 649 ℃ respectively. The tensile strength of the fiber is 2.1 GPa. After the aging test at 300 ℃ for 24, 48, and 72 h, the retention rates of tensile strengths reach 99.8%, 87.3%, and 76.3% respectively. At the same time, polyimide fiber has excellent dimensional stability, and its thermal expansion coefficient is -9.1 μm/(m·℃) in the range of 50-350 ℃.

Key words: polyimide, dry spinning, high performance fiber, thermal stability, thermal aging test
