MANUFACTURING APPARATUS FOR REGENERATED CARBON FIBER, MANUFACTURING PROCESS FOR REGENERATED CARBON FIBER, AND REGENERATED CARBON FIBER

WIPO Patent Application WO/2013/168302

A1

[Problem] To provide: an apparatus for manufacturing a regenerated carbon fiber having excellent handleability from a carbon fiber reinforced plastic (CFRP) as raw material; a process for manufacturing the regenerated carbon fiber; and a regenerated carbon fiber. [Solution] A carbon fiber manufacturing process (1) includes principally: a packing step (S3) for packing a heating cage (10) with a CFRP (25) in a prescribed bulk density; a heating cage conveying step (S5) for introducing the heating cage (10) into a regeneration treatment section (3) having a regeneration treatment space (2); a heating/removing step (S6) for heating the CFRP (25) in a heating/removing section provided in a heating zone and thereby removing the matrix components with a part thereof left as fixed carbon; and a cooling step (S7) for cooling the resulting regenerated carbon fiber (8) having fixed carbon adhering thereto. In the regenerated carbon fiber (8) manufactured by this manufacturing process with this manufacturing apparatus, the ratio of carbon remaining as fixed carbon is 0.5 to 11.0 wt%, said carbon being resulting from the matrix components of CFRP.
