【摘要】 为选择适于作为碳纤维原料的煤沥青，对三种中低温煤沥青的预处理和组成结构进行了研究，同时对其中的太钢煤沥青进行了热缩聚制取中间相沥青的结构变化分析。研究分析结果表明，只要经过合适的工艺路线进行处理，这三种煤沥青都有可能作为沥青基碳纤维的原料。更多还原

【Abstract】 In order to select appropriate coal pitch as material of carbon fiber, pretreatment,composition and structure of three kinds of mid-low temperature coal pitches were studied in this paper. At the same time, the structure analysis of mesophase pitch thermopolymerized by coal pitch from Taiyuan Iron and Steel Company was made,The results indicate that three kinds of coal pitches can all become material of coal pitch carbon fiber through suitable technological process.更多还原
