Abstract: Aromatic polyamide fibers have broad applications in military and civilian fields, due to their excellent advantages such as ultrahigh strength and modulus, light weight, heat-resisting, impact and fatigue resistance. However, owing to the large number of chromogenic groups in the molecular structure, aromatic polyamide fibers easily absorb ultraviolet radiation and cause irreversible photo-aging damage, which restricts their service performance. This paper summarizes their ultraviolet sensitivity characteristics, photo-aging mechanism, and highlights the current main anti-ultraviolet aging modification methods.

Key words: aromatic polyamide fiber, anti-ultraviolet aging, photo-aging mechanism, modification, composites
