The laminate is then fused to the support structure using a non-contact heating process, such as inductive welding.

Abstract: A method for manufacturing a carbon fiber is provided which involves: (1) immersing a carbon fiber composite material (CFC) in an acidic aqueous solution to elute at least a part of a resin component of the CFC, to thereby obtain a substantially fibrous product; and (2) immersing the substantially fibrous product obtained in step (1) in an alkaline aqueous solution to elute at least a part of a resin component of the substantially fibrous product, to thereby obtain a fibrous product. A method for manufacturing a carbon fiber reinforced resin composition is provided which involves manufacturing a carbon fiber by the above method and manufacturing a carbon fiber reinforced resin composition using the resulting carbon fiber. Using these methods, it is possible to recover and recycle a carbon fiber from a carbon fiber composite material (CFC) at a low cost without deteriorating the carbon fiber.
