Abstract

Processes for forming recyclable carbon-fibre-reinforced composites comprise the following steps. Provide a reinforcement structure (52) formed from a plurality of carbon fibres, the carbon fibres being treated carbon fibres having an outer surface possessing a mechanical roughness formed as a result of a treatment. Then, infiltrate the reinforcement structure with a liquid thermoplastic precursor (54). Then, polymerise the liquid thermoplastic precursor (56), thereby encapsulating the reinforcement structure with a thermoplastic matrix to form the recyclable carbon-fibre-reinforced composite. Recyclable carbon-fibre- reinforced composites are made using these processes.
