carbon fibre is a strong reinforcing agent for composite materials, and is normally used in the shape of filament. milled fibre, also has prospects because it is suitable for extrusion moulding. although the strength of carbon fibre composites depends on the interfacial adhesiveness between fibre and matrix as well as their own strength, it is commonly seen that raw carbon fibre has poor wettability and dispersibility with a polymer matrix. to enhance the interfacial adhesion with the matrix, in particular with epoxy resin, the formation of oxygen-containing groups on the fibre surface is effective. this letter presents preliminary results of plasma oxidation of milled carbon fibres, demonstrating the advantages of fluidized-bed processing. the treated fibre was characterized by x-ray photoelectron spectroscopy (xps), scanning electron microscopy (sem) and measurement of the contact angle as a function of the radio frequency r.f.) discharge power. 9 refs
