Description

<p>Raw materials for pitch-based carbon fiber were derived from coal and petroleum. These raw materials and the carbon fiber precursors prepared from the raw materials are complex mixtures of heavy hydrocarbons. Average molecular structure analysis of the raw materials and the precursors is important to develop high-quality carbon fibers. In this study, we investigated the changes in molecular structure during the preparation of precursors and the differences between the coal-based and petroleum-based precursors.</p>
