| titleOfInvention | Process for producing pitch-based carbon fibers superior in compression characteristics |
| abstract | Pitch-based carbon fibers superior in compression characteristics are obtained by mixing a polycyclic aromatic compound and a hydrogen donating compound at a mole ratio of the latter to the former in the range of 0.1 to 10, polymerizing the resulting mixture at a temperature of 50° to 400° C. in the presence of a Lewis acid as catalyst, then removing the catalyst, thereafter heat-treating the resulting polymer to obtain a pitch containing 5-40% of anisotropic spheres of 5-60 μm, having a total amount of aliphatic hydrogen of 25-50% and an amount of aliphatic hydrogen after β of 5-25% and containing not more than 30% of oriented carbon based on a total amount of aromatic carbon, then spinning said pitch, then making the resulting pitch fiber infusible and subjecting the pitch fiber thus rendered infusible to a carbonization treatment. |
