Abstract

Carbon fibre is subjected to a surface removal step (e.g. with nitric acid) followed by a surface deactivation step. The surface deactivation step comprises either removing at least some of the functional groups on the surface of the fibre (e.g. by heating in N2 at 530 DEG C) or rendering those functional groups incapable of forming a chemical bond with a resin matrix material e.g. by coating the fibre with polyethylene. When such treated fibres are incorporated in a resin matrix, the resultant composite material is provided with enhanced strength properties when compared with similar composite materials containing untreated carbon fibres.
