酚醛基碳纤维制备方法研究进展

摘要

对近年来酚醛基碳纤维的熔融纺丝、湿法纺丝、静电纺丝和离心纺丝等制备方法的研究现状进行归纳总结并分析了各自的优缺点.指出未来在开发高性能、功能化的酚醛基碳纤维及酚醛基碳纤维增强复合材料的研究过程中,应从原丝结构、工艺过程和产品种类三个方面进行开展.%The preparation methods of phenolic resin based carbon fiber including melt spinning,wet spinning,electro-spinning and centrifugal spinning are summarized and the advantages and disadvantages of each method are analyzed.It is pointed out that the research of high-performance,functional phenolic resin based carbon fiber and phenolic resin based carbon fiber reinforced composite materials should be further studied from three aspects:the structures of phenolic resin precursors,technical process and product types.
