摘要：
Fiber-reinforced polymer composites (FRPC) which have excellent properties such as high strength, easy processing and low cost are the preferred structural materials for typical industrial products such as wind turbines and circuit boards. With the increase in FRPC production year by year and the arrival of decommissioning period of industrial products, the accumulation of discarded composite materials will lead to serious environmental pollution and waste of energy and resources, thus it is urgent to develop efficient and clean recycling technologies. Chemical recovery technology can not only recover high-quality fiber materials, but also realize the targeted conversion of resin into fuel and organic chemicals. Based on the analysis of composition characteristics of composites wasted and chemical recovery technologies, this article evaluates the application of recycled products, technical economy and environmental benefits. It is further proposed that based on the characteristics of the functional groups of organic resins, the non-destructive recycling of fiber materials can be realized while producing fine chemicals through directional depolymerization and upgrading cycle under mild conditions. © 2023 Chemical Industry Press.
