Carbon fiber reinforced plastic (CFRP) has been widely and rapidly used in aircraft, automobile and various field due to their light weight and excellent properties. Since the service life of CFRPs is approximately 50 years, the extensive use of CFRP is now starting to produce serious waste disposal problems. The properties of infusibility and insolubility in organic solvent of cured epoxy resin makes it impossible to recycling of CFRP. In the conventional chemical recycling, CFRPs were also crushed into small pieces and carbon fibers are recycled by pyrolysis processes or chemical treatment. The existing CFRP recycling technology uses high temperature pyrolysis method. However, in case of thermal pyrolysis, multiple toxic chemicals are generated that can create further environmental problems. In this study, we have succeeded in chemical recycling of CFRP using aqueous solution. We were able to recover high quality carbon fiber and recycle the decomposed epoxy resin. |
