A promising strategy for chemical recycling of carbon fiber/thermoset composites: self-accelerating decomposition in a mild oxidative system

An efficient solution has been built for the chemical recycling of carbon fiber/epoxy composites by oxidative degradation under mild conditions with acetone and H2O2. Clean CF can be obtained after reacting at 60 °C for 30 min. The decomposition ratio of epoxy is above 90%, and the strength of CF remains more than 95% of its original strength.
