Title: Production of carbon and graphite fiber
Inventor: KURODA HIROYUKI
IPC: D06M13/51
Filed: 1986-06-09
Abstract: PURPOSE:To obtain pitch based carbon and graphite fibers having a good external appearance and high strength and elastic modulus, by doubling spun fiber, applying a heat-resistant oiling agent containing an infusibilization accelerator thereto, passing the resultant fiber bundle in a linear form through a continuous infusibilization furnace and infusibilizing the fiber bundle. CONSTITUTION:Carbonacceous pitch is melt spun to give pitch fibers, which are then doubled. A heat-resistant oiling agent prepared by dissolving a cobalt salt as an infusibilization accelerator for fiber bundling is applied to the doubles fibers. The resultant fiber bundle in a linear form is then continuously passed through a continuous infusibilization furnace containing an oxidizing atmosphere and infusibilized. The infusibilized fibers are further carbonized and graphitized in an inert gas atmosphere. The fiber bundle is not broken infusibilization and the amount of the bundle infusilizable at a time can be increased.
