biostudies-literatureUnknown10(36)Sagredo-Acitores MThe 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 thosACS omega41302-41309https://www.ebi.ac.uk/biostudies/studies/S-EPMC12444513biostudies-literatureRecycling of Carbon Fiber-Reinforced Epoxy Resin by Sustainable Solvolysis.PMC12444513Garcia-Arrieta SSagredo-Acitores MSanchez-Cupido LAldana-Martinez JLde la Calle AOllo OSantos-Moreno SfalseRecycling of Carbon Fiber-Reinforced Epoxy Resin by Sustainable Solvolysis.The increasing demand for epoxy-based carbon fiber-reinforced plastics (CFRPs) has led to significant waste generation and environmental concerns.
