Abstract
The surface modification of carbon fibres by gamma-irradiation at different dose levels followed by grafting with chloroepoxypropane, and characterisation of the fibres by SEM (surface morphology), dynamic contact angle analysis (surface free energy) and single fibre tensile testing before and after surface treatment, is described. The effects of irradiation dose on the interlaminar shear strength of composites of diglycidyl ether of bisphenol A-based epoxy resin with the modified fibres were investigated by short-beam flexural testing, and the results are discussed in terms of interfacial adhesion and the formation of covalent bonds between fibres and grafting agent. 18 refs.
