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.

Key words: fiber-reinforced polymer composites, chemical recovery, pyrolysis, solvolysis method, regeneration, economic and environmental assessment


纤维增强树脂复合材料(fiber-reinforced polymer composites,FRPC)具有强度高、易加工、成本低等优异性能,成为风机叶片、线路板等典型工业产品的首选结构材料。随着FRPC产量逐年增加以及工业产品退役期的来临,废弃复合材料的累积将导致严重的环境污染和能源资源浪费,亟需研发高效清洁回收技术。化学回收技术不仅能够回收高质纤维材料,而且可实现树脂定向转化为燃料和有机化学品。本文在分析复合废材组成特性以及化学回收技术的基础上,对再生产品应用、技术经济性以及环境效益进行了评价。进一步提出基于有机树脂官能团特性,在温和条件下定向解聚升级循环制备精细化学品的同时,实现纤维材料无损再生利用。
