Abstract: Recent supply chain shortages, particularly virgin carbon fiber shortfalls, have advanced technological solutions to recover and reuse carbon fibers from waste composites. We present catalytic, aerobic conditions for depolymerizing amine-linked epoxy thermoset matrix polymers commonly used in high-performance carbon fiber-reinforced polymer (CFRP) materials. Unlike other recycling methods, this process preserves the fibers aligned and woven in the same pattern as the parent material and returns valuable materials from the thermoset matrix. Preliminary life-cycle analyses of this process relative to existing technologies reveal an opportunity to reduce energy investment in virgin carbon fiber manufacturing by 54% if executed at scale.
