With the development of industries such as aerospace, automobiles, wind power and the like, the demand of the carbon fiber cloth is increased year by year. The usage amount of the carbon fiber reinforced resin matrix composite material in 2018 is about 12.8 ten thousand tons, and the annual demand of the carbon fiber reinforced resin matrix composite material in 2022 is estimated to reach 19.9 ten thousand tons; in addition, the cumulative amount of carbon fiber composite used worldwide was about 705 ten thousand tons in the past decade. During the production of carbon fiber composite products, about 30% of the raw material becomes waste.
