摘　　要：从物理法和化学法角度对热固性树脂基复合材料国内外回收方法的研究进展进行了综述,重点介绍了高温热解法、流化床热解法、微波热解法、硝酸氧化法、溶剂分解法及近几年兴起的超/亚临界流体技术、绿色氧化法和源头设计法等化学回收方法及所取得的进展和成果,对碳纤维增强复合材料的高值回收前景进行了展望。指出没有一种方法能解决所有复合材料的回收问题,必须根据复合材料本身的特点发展合适的系统解决方案。The physical and chemical methods for fiber reinforced thermosetting resin based composites recycling were reviewed.It was emphasized that the progress and achievements of some conventional technologies and innovative processes, including pyrolysis at high temperature, fluidized bed processing, microwave heating, oxidation using nitric acid, solvolysis, supercritical fluid technology, green oxidation, source design, etc.The prospects for the application of chemical recycling carbon fiber with high quality were also discussed.It was concluded that there was no universal method to recycle all of the composites.It was also suggested that the systemic recycling approach should be developed according to the specific characteristics of each composites.
