ABSTRACT:
A method of manufacture of pitch-based carbon fiber by infusibilization of pitch fiber followed by carbonization, comprising doping the pitch fiber with at least 0.05 percent by weight of iodine, heating under an oxidizing atmosphere for infusibilization, and then heating under an inert atmosphere for carbonization, whereby it is carbonized or graphitized.
