摘　　要：介绍了低相对分子质量酚醛树脂的制备方法及酚醛纤维的熔融纺丝、湿法纺丝及熔喷纺丝等制备工艺;分析了酚醛纤维的改性机理及其在力学性能、氧化性能和热性能、碳纤维活化方面的改性方法,比较了多种改性方法对纤维最终力学性能和阻燃性能的影响;展望了酚醛纤维发展趋势,指出高邻位酚醛纤维将是未来酚醛纤维研究开发的方向。The production technologies of low-relative molecular mass phenolic resins were introduced, as were the production processes of phenolic fibers including melt spinning, wet spinning and meltblown spinning. The modification mechanism and technologies of phenolic fibers were analyzed to improve the mechanical properties, thermal and oxidation behaviors and carbon fi- ber activation. The effects of modification technologies on the mechanical properties and flame retardance of the resulted fibers were compared. The development trend of phenolic fibers was outlooked. It was pointed out that the research development of phenolic fibers be focused on high-ortho phenolic fibers in the future.
