there have been many studies of the chemical changes induced by oxidative treatments of carbon fibre surfaces attempt to understand the nature of fibre/matrix interactions in carbon fibre/epoxy composites. however, there are conflicting reports on the amount and type of oxygen and nitrogen functionality induced by similar surface treatments. this arises because most commercially successful treatments only alter the first few atomic layers of the fibre itself and signals from these functional groups are swamped by the graphitic backbone in the carbon ls spectrum. it is shown, that by using the small spot and small acceptance angle features of the phi 5400 x-ray photoelectron spectrometer signals from these surface features can be enhanced. 7 refs
