ABSTRACT:
A method of treating carbon fibre in which the fibre is subjected to a surface removal step 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 or rendering those functional groups incapable of forming a chemical bond with a resin matrix material. 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.
