沥青基碳纤维的研发及产业化

Research and industrialization of pitch based carbon fiber

沥青基碳纤维是碳纤维的一个重要品种,但我国在沥青基碳纤维的研发和生产较国外还有很大差距。介绍了我国沥青基碳纤维研发和产业化现状,就其中的关键工艺(纺丝沥青调制和熔融纺丝)进行了综合分析。通用级沥青基碳纤维在国内已有一定的科研和生产基础,近期可望完成自主技术工业化装备的建立和生产;高性能沥青基碳纤维的研发虽然较为充分,但用于纺丝的中间相沥青的制备和连续长丝工艺的开发还要经过努力才能实现产业化,以摆脱美日的技术和产品的封锁。

Pitch based carbon fiber is one of important products of carbon fibers.However,the research and production of pitch based carbon fiber in our country are far behind these abroad.Research and industrialization of pitch based carbon fiber in China were introduced in the article.Some key processes,such as preparation and melt spinning,were overviewed.China has some experience on study and production of general purpose pitch based carbon fiber.It could be predicted that recently industrial facilities would be made and production would begin on the base of ourselves technology.Although high performance pitch based carbon fiber was studied deeply,the preparation of mesophase pitch for melt spinning and process for long continuous carbon fiber should be given great efforts to industrialize.The blockage of technology and products could be broken through.
