摘　　要：主要综述聚酰亚胺纤维的国内外发展概况,产业现状以及其耐高温、耐辐射、耐溶剂、高强高模、阻燃等基本特性,重点阐述了其本质阻燃特性,包括极限氧指数及其在高温下的稳定性。近年来国内外对聚酰亚胺纤维的阻燃改性研究有所增加,主要包括引入磷元素、氟元素以及有机硅等体系。与其他阻燃纤维对比发现,聚酰亚胺纤维在高温防护、高温过滤等领域具有明显的优势,可成为较好的高温阻燃材料。This overview discusses the development of polyimide fiber both at home and abroad,the current status of the industry,and basic properties such as high temperature,radiation and solvent resistance,high strength,high modulus,and flame retardance with focus on its inherent flame retardance,including the limited oxygen index and high temperature stability.There is a growing trend in the flame retardant modification research of polyimide fiber all over the world in recent years,chiefly aiming at introduction of phosphorus,fluorine,and organic silicon into the fiber.It is found by comparison with other flame retardant fibers that polyimide fiber has obvious advantages in the fields such as high temperature protection and filtration,and is suitable for use as high temperature flame retardant material.
