Abstract
PURPOSE: A depolymerization product from coal is used as the starting material and melt spun, thus facilitating the infusible treatment and producing fibrous carbon in increased carbonization yield.
CONSTITUTION: A coal-depolymerization product resulting from treating coal with a solvent under pressurized hydrogen, preferably softening at 200W250°C and containing less than 0.5wt% of insoluble solid, or a mixture thereof with a bitumen with high aromaticity as solid part-removed coal tar pitch or petroleum pitch at a ratio of 1:0.05W1 is used as the starting material and melt spun at a temperature 30W70°C higher than the softening point. Then, infusible treatment is effected by heating from room temperature up to a temperature 60W80°C higher than the softening point at a temperature-rising rate of 3W10°C/min. The resulting fibers are baked by heating at a rising rate of less than 20°C/min up to 1000°C to effect carbonization, thus giving the objective carbon fibers.
