    摘要: Nonflammable fibers are produced by subjecting a composite fiber comprising a pitch and a synthetic organic polymer bonded uniformly along the longitudinal direction of the fiber to an oxidation treatment to render it infusible and then to a set treatment in air or gaseous nitrogen at a temperature of 200* to 500* C. for at least 2 hours. The nonflammable fiber is converted to carbon fiber by heating to a temperature higher than 800* C. in gaseous nitrogen. Suitable pitches include petroleum asphalt, coal tar pitch, and pitch obtained by baking polyvinyl chloride. Suitable synthetic organic polymers include polyamides, polyesters, polyolefins, polyvinyl chloride, polyvinylidene chloride, polyurethane, epoxy resins, and phenol resins.

    摘要: A process for the production of carbon fibers from coal-tar pitch or from other strongly aromatic distillation residues wherein an oxygen-containing polymer is added to the starting material before or during the heat treatment which is followed by the usual stages of spinning, oxidizing and carbonizing.
