TL;DR: In this paper, an amine-cured epoxy resin was decomposed by a supercritical solvent (methanol, 1-propanol, 2-polypanol and 1-butanol) at 320°C in the reaction time range 6-120 min.
Abstract: Chemical recycling of carbon fiber reinforced plastic (CFRP) containing an amine-cured epoxy as the matrix resin was investigated with a process using supercritical alcohols or ketones as solvents. Amine-cured epoxy resin was decomposed by a supercritical solvent (methanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, tert-butanol, acetone, or methyl ethyl ketone) at 320 °C in the reaction time range 6–120 min. The decomposition rate depended on the solvent, and super- and subcritical acetone were ultimately selected as optimal for rapidly degrading the matrix resin. The decomposition rate of the epoxy resin using supercritical acetone was expressed by a surface reaction and shrinking core model. The recovered carbon fibers from the CFRP retained the shape of the plain fabric sheets and their tensile strength reduction was negligible.

TL;DR: The rates of desirable reactions relative to undesirable pathways (HMF rehydration and polymerisation) were comparable among these mediums and higher selectivity towards HMF production over the side reactions than THF/H2O.
