Recovery and reuse of carbon fibre and acrylic resin from thermoplastic composites used in marine application

The development of new sustainable routes towards better environmental footprint composites for marine boatbuilding is motivated by the absence eco-friendly and economically viable recycling techniques to deal with growing end-of-life thermoset boats waste increasing restrictive legislation. Thermoplastic may offer possibility recover raw materials from retired parts, which could have a substantial economic benefit. This study investigates feasibility recovery reuse both reinforcement matrix carbon fibre reinforced thermoplastic Elium composite. An original pyrolysis process allowed depolymerisation acrylic clean fibres monomer. Distillation was used purify monomer impurities recycled resin synthesized reused as long aligned reinforcement. morphological composition differences at scale resulted in concluding that sizing has been decomposed during only small traces polymer were left on surface. Virgin laminates produced infusion. While tensile modulus, strength strain break nearly unchanged, interlaminar shear results showed enhanced fibre-matrix interphase bonding. Dynamic mechanical analysis confirmed good quality recovered well similar virgin re-polymerised properties. composite made be same application field.
