Abstract: The present embodiment is a method of recycling reinforcing fibers, the method comprising: providing a tank having at least a first protective layer disposed on an outer peripheral surface of a liner and a liner, the first protective layer being configured such that a resin-impregnated fiber bundle including a reinforcing fiber bundle and a first matrix resin is wound around the liner; and a second protective layer formed of the first matrix resin on the first protective layer; removing a portion of the second protective layer to expose a winding end portion of the resin-impregnated fiber bundle; peeling the exposed winding end portion; and pulling the peeled winding end portion to draw out the resin-impregnated fiber bundle.

Abstract: Provided is a method of recycling carbon fibers that allows obtaining continuous carbon fibers. The present embodiment is a method of recycling carbon fibers that includes preparing a carbon fiber reinforced plastic molded product including carbon fiber reinforced plastic containing carbon fibers and a resin and drawing the carbon fiber reinforced plastic while performing a heating treatment on the carbon fiber reinforced plastic molded product. A temperature of the heating treatment is equal to or above a glass-transition temperature of the resin and below a thermal decomposition start temperature, and the temperature is below a thermal degradation temperature of the carbon fibers.
