Recyclable Vitrimer-Matrix Carbon-Fiber Composites for Aerostructures: Reprocessing Efficiency and Retention of Mechanical Performance
Abstract: To begin with, carbon fiber reinforced polymers (CFRP) have become an important part of the structural loading in many modern aircraft; however, due to their permanent cross-linking in thermosets, they cannot easily be restored after being retired. Vitrimers have been proposed as a solution since their Covalent Adaptable Networks (CANs), rearranged by associative exchange, may be reshaped, welded, repaired or dissolved without damaging the CFRP fibers. This paper reviews whether …
