Abstract: In this paper,three methods of composite scrap recycling technology including mechanical recycling, thermal recycling and chemical recycling were introduced. The current development of the fluidised bed,pyrolysis, and solvent solution of the chemical technology to recycle and reuse composite scrap at domestic and abroad were briefly elaborated. Under the guidance of the policies of china,new technologies of low power consumption and high recovery of fiber should be greatly developed to recycle and reuse composite scrap.

Key words: composite scrap, fiber recycling, fluidised bed method, pyrolysis, solvent solution
