Recycling of Carbon Fiber-Reinforced Epoxy Resin by Sustainable Solvolysis.

ABSTRACT: The increasing demand for epoxy-based carbon fiber-reinforced plastics (CFRPs) has led to significant waste generation and environmental concerns. To address this issue, a novel, recycling method has been developed using a mixture of methyl ethyl ketone (MEK) and hydrogen peroxide (H₂O₂) as a solvent system. This approach selectively decomposes the epoxy resin matrix under mild conditions, recovering carbon fibers with minimal damage. Optimal conditions for resin decomposition were identified at 70 °C for 12 h with a liquid-solid ratio of 15 in a MEK/H₂O₂/H₂O molar ratio of 1/1/4, achieving a decomposition ratio of up to 95%. The recovered carbon fibers were used to create new composites, which showed similar tensile properties to thos
