摘要: 芳香族聚酰胺纤维因具有高强高模、轻质耐热、抗冲耐磨等优势,被广泛应用于军民两用领域。由于分子结构中存在大量的生色基团,芳香族聚酰胺纤维易吸收紫外辐射而引发不可逆的光老化损伤,制约其使役性能。本文概述了芳香族聚酰胺纤维的紫外光敏特性,分析总结了其光老化机理,并重点介绍了目前抗紫外老化的主要改性研究方法。

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
