Carbon fiber products with the same properties as Toray T300 carbon fiber were prepared from 1K PAN based precursors with two different processing routes.However,there were significant differences in pre oxidation process between the two precursors.FT-IR,DSC,SEM,OM and other analytical methods were used to compare and analyzed the composition and performance between the two kinds of precursors.It was indicated that the component difference of precursor was the essential cause of the difference of pre oxidation process of fiber,and the analysis of precursor for different precursor needed to be made before carbonization process,which was beneficial to the rationality and accuracy of process condition.
