Non-fusible Treatment of Mesophase Petroleum Pitch Fibre

Influence of mesophase content, oxidation temperature and oxidation residence time on the non fusible treatment of mesophase petroleum pitch fibre was investigated under air atmosphere. The non fusible pitch fibre was carbonised in nitrogen atmosphere. Yield rate and tensile strength of the carbon fibre were detected. The results indicate that under the same oxidation temperature, the non fusible treating time is shortened with the increase of the mesophase content.
