Thermo-oxidative Aging Behavior of Ultra-high Molecular Weight Polyethylene Fiber and Its Composites

doi:10.12382/bgxb.2021.0638

Abstract

Abstract: The structure and performance of UHMWPE fibers and UHMWPE fiber/SEBS composites before and after thermal oxygen aging were analyzed by FTIR, DSC, DMA, universal testing machine and SEM. The results show that the mechanical properties of the UHMWPE fiber after aging are closely related to the thermo-oxidative aging temperature; the tensile strength of the fiber decreases significantly after high-temperature thermo-oxidative aging, but the crystalline structure of the fiber is not affected; the interface of fiber and resin of UHMWPE fiber/SEBS composites was damaged after thermal-oxidative aging at 70 ℃ and 90 ℃ for 336 h (2 weeks); the flexural strength and flexural modulus of the composites decreased 28% and 49% respectively after thermal-oxidative aging at 90 ℃ for 672 h (4 weeks). However, after 8 weeks of thermo-oxidative aging at 50 ℃, 70 ℃ and 90 ℃, the retention rate of the ballistic limit velocity v₅₀ using 1.1 g standard simulating fragments against the composites was higher than 95%.
