Abstract

Co⁶⁰ γ-ray irradiation as a novel method for modification of carbon fiber (CF) surface was introduced in this paper. After surface treatment by mutual irradiation the interlaminar shear strength (ILSS) of CF/epoxy composites was enhanced by about 37%. Surface elements of CF were determined by XPS analysis, which indicated that the oxygen/carbon ratio increased rapidly. Fitting the C 1s spectra demonstrated that two new photopeaks were emerged which was indicated CO and plasmon, respectively. Surface topography of carbon fibers was analyzed by atomic force microscopy (AFM). It could be found that the degree of surface roughness was increased by lower absorbed dose (30 kGy), but excessive irradiation (>250 kGy) was not beneficial for mechanical interlocking between CF and epoxy resin. The impregnating performance of CF was also improved after irradiation.
