高性能纤维的发展现状及展望

Review on the development of high performance fiber

为系统了解高性能纤维的优异特性及其市场应用情况,分析了碳纤维、芳纶、超高分子量聚乙烯纤维、聚酰亚胺纤维、聚苯硫醚纤维5种代表性高性能纤维的性能特征及其应用领域;阐述了这5种高性能纤维的市场现状及存在的问题,并指出未来研发方向。研究认为:我国碳纤维应加大对大丝束、低成本产品的研发,间位芳纶及超高分子量聚乙烯已具备一定的竞争力,但对位芳纶及聚苯硫醚纤维进口依赖严重,聚酰亚胺纤维的整体市场容量有限。

In order to understand the market application of high performance fiber,the performance characteristics and application fields of five representative high performance fibers including carbon fiber,aramid fiber,ultra high molecular weight polyethylene fiber,polyimide fiber and polyphenylene sulfide fiber were analyzed.The market status and existing problems of these five kinds of high-performance fibers were described,and the future research and development direction was put forward.It is considered that the research and development of large tow and low-cost products for carbon fiber should be increase,meta aramid fiber and ultra-high molecular weight polyethylene have certain competitiveness,but para aramid fiber and polyphenylene sulfide fiber are heavily dependent on imports,and the overall market capacity of polyimide fiber is limited.
