Waste carbon fiber-reinforced polymer (CFRP) composites have caused economic and environmental problems. Thus, the development of an effective method for the recycling of such waste is needed. In this study, the superheated steam-induced degradation method was chosen for removal of epoxy from waste CFRP. The degradation products were analyzed by GC-MS. In order to more clearly understand the degradation mechanism, model epoxy materials were prepared using diglycidylether of bisphenol A and diaminodiphenyl methane as an oligomer epoxy resin and a curing agent, respectively. We attempted to prepare epoxy curing agents using the recovered materials along with appropriate amounts of amines. An epoxy resin was cured using the curing agents, and the resulting cured epoxy was analyzed with differential scanning calorimetry and dynamic mechanical analysis. The experimental results will be presented in detail |
