【 摘 要 】

Thermotropic liquid crystalline polyarylate fiber is a kind of high performance fiber with high strength and modulus, high temperature and chemical resistance. In this paper, TLCPAR fibers were prepared by melt spinning and then heat-treated. The effects of spinneret draft ratio, heat-treatment temperature on aggregate structure and mechanical properties of the fibers were investigated.
