提升杂环芳纶复合性能的研究进展
Advancement in enhancing composite performance of heterocyclic aramid fibers
摘要
Abstract
Heterocyclic aramid refers to a type of para-aramid containing aromatic heterocycles(usually benzimidazole units)in the main chain,which has excellent properties of lightweight,high strength and modulus,high thermal resistance and good solvent resistance.Compared to the typical aramid fiber Ⅱ,heterocyclic aramid exhibits superior mechanical properties and has been practically applied in the fields such as aerospace and bulletproof protection in China.However,similar to other organic fibers,the composite performance of heterocyclic aramids with resins is relatively low due to their inert surface,which limits their application in the field of advanced composite materials.This article from two aspects of surface modification and structural design,the design ideas,technical means and research results to enhance the composite performance of heterocyclic aramids in recent years are summarized,and the development trend of its application in the field of advanced composite materials is forecast,so as to provide assistance and reference for the interface design and improvement of interfacial adhesion of organic fibers.关键词
