2026-047- Closed-Loop Prepreg Recycling for Fiber and Monomer Recovery

Background Carbon fiber prepregs are widely used in aerospace and high-performance manufacturing since they can produce lightweight, high-strength composite structures. However, prepregs have a limited storage life, and an estimated 30–50% of prepreg material used is ultimately discarded due to expiration or manufacturing scrap. A recycling solution...

2023-132 - A rapid electrochemical method to recycle carbon fiber composites

Background Thermoset carbon fiber–reinforced polymer (CFRP) composites are popular for their exceptional specific modulus and strength, leading to a projected global demand of approximately 285,000 tons annually. A recycling method recovers the embedded carbon fibers, and post-processing recovers valuable resin monomers. Technology Description...
