Abstract

Abstract : Carbon‐fiber reinforced composites are prepared using catalyst‐free malleable polyimine networks as binders. An energy neutral closed‐loop recycling process has been developed, enabling recovery of 100% of the imine components and carbon fibers in their original form. Polyimine films made using >21% recycled content exhibit no loss of mechanical performance, therefore indicating all of the thermoset composite material can be recycled and reused for the same purpose.
