Abstract

The invention discloses a reinforcement mode based high-performance fiber reinforced resin based composite material recovery method. The method is characterized in that the reinforcement mode comprises reinforcements before and in a supercritical reaction. The method which adopting the reinforcement mode greatly reduces the energy consumption in the reaction process, improves the recovery efficiency, and reduces the recovery treatment cost of a high-performance fiber reinforced resin based composite material; the decomposition rate of a resin matrix is greater than 95%, and the decomposed resin matrix can be reused as chemical engineering raw material; and the loss of the mechanical performances of high-performance fibers recovered in the invention is less than 5%, there is almost no residual on the surface, the recovered high-performance fibers can be reused for producing the composite material, and the resource properties are high.

Description

technical field

[0001] The invention relates to a method for recycling composite materials, in particular to a method for recycling high-performance fiber-reinforced resin-based composite materials using a supercritical method, which can be used in the field of recycling of high-performance fiber-reinforced resin-based composite materials. Background technique

[0002] High-performance fiber-reinforced resin-based composites have been widely used in aerospace, automobile, wind power and other fields due to their excellent corrosion resistance, thermal stability, high strength and impact resistance. The recovery and recycling of leftovers, defective products, structural parts damaged during use, and scrap products beyond their service life are becoming a key issue. The annual output of composite materials in the world exceeds 5 million tons, the waste is as high as 1 million tons, and the recycling rate is only 10%. The recycling and reuse of high-performance fiber-reinforce...
