제목 Chemical Recycling of CFRP using Aqueous Solution
초록 CFRP (Carbon Fiber Reinforced Plastic) is a composite material in which carbon fiber with high strength and lightweight is hardened with epoxy resin matrix. CFRP weighs only a quarter as much as steel, but is 10 times stronger. Currently, its usage is expanding from cutting edge technology in aerospace industry and general industry. However, the properties of infusibility and insolubility in organic solvent of cured epoxy resin makes it impossible to recycling of CFRP. 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. Moreover, this method has a limitation that it cannot recycle the epoxy resin which occupies a large amount of the composition of CFRP. 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.
