Researchers at USC have created a method to recycle carbon fiber reinforced polymers (CFRPs) used in automobiles, preserving the integrity of both carbon fibers and the polymer matrix.

The upcycling method saves the carbon fibers of the CFRP, which are the strong, durable part of the material. These fibers stay in good condition, and the team showed how they can be reused in new manufacturing, keeping over 97% of their original strength. This method is the first to successfully claim value from both the matrix and carbon fiber parts of CFRPs, turning waste into useful products and reducing environmental harm.
