沥青基炭纤维(Pitch Based Carbon Fiber) () 摘要: 沥青基炭纤维是以燃料系或合成系沥青原料为前驱体,经调制,成纤,烧成处理而制成的纤维状炭材料.沥青炭纤维在20世纪60年代初由日本学者大谷杉郎首先研制成功,并于1970年由日本吴羽化学工业公司进行工业化生产.此后,由于碳质中间相的发现和"液相炭化"工艺的开发,特别是美国学者Singe等人在70年代用中间相沥青制造高性能连续沥青炭纤维工艺的开发成功,使沥青炭纤维的研究开发进入了一个新的阶段.由美国联合碳化物公司(UCC)制造的以"Thornel-P"为代表的高性能级沥青炭纤维问世,标志着沥青炭纤维工艺趋于成熟,成为继聚丙烯腈基炭纤维之后又一新型炭纤维材料.
