In this work, we report the change of wetting and interfacial bonding of T800S carbon fibre recycled using a pyrolysis process. A low cost epoxy resin and a low cost vinyl ester resin were used for the assessment. These two low cost resins would be candidates for manufacturing recycled carbon fibre reinforced polymer composites for the automotive industry. 

Licea-Claverie and co-workers [57] studied mechanical stress-strain, impact properties and also thermal properties of PA 6,6 (including some recycled PA) with mixed glass fibre and carbon fibre reinforcements and compared these properties with those of the virgin polymers. No dependence on mechanical properties because of increasing amounts of scrap in the composites was found up to 10.4 wt%. The recycled composites generally showed lower mechanical properties when compared with the virgin composites because of a poor matrix-fibre adhesion.
