AB  - Gamma irradiation to various doses (4.8-27.2 MGy) was performed on unidirectional carbon fiber/epoxy resin composite plates. Unidirectional composite coupons irradiated to various doses were annealed at 180 and 250 degrees C, in vacuum. The strain energy release rate G(IC), as a measure of delamination fracture toughness, was determined by Mode I fracture testing on double cantilever beam coupons. The glass transition temperature (T(g)) of the tested coupons matrices was determined in DMA tests. The effects of irradiation and annealing on G(IC) values - the mean values of 10 propagation points (G(IC),(mean)) and that of fracture initiation (G(IC,init)) - were established. These values were analyzed as a function of irradiation dose and annealing temperatures, having in mind glass transition temperature values changes, as well as the possible mechanisms and phenomena of irradiation and annealing.

AB  - The paper reports on an experimental study of the Mode I interlaminar fracture of unidirectional carbon fibers/epoxy resin composites. Mode I delamination strain energy release rate G(IC) was determined in double cantilever beam (DCB) test, before and after gamma irradiation at various doses. Glass transition temperature, T-g of epoxy matrix was determined from dynamic mechanical measurements. The delamination surfaces of tested coupons were observed by scanning electron microscopy. The variations in G(IC) values were correlated with irradiation doses, T-g values and the features of delamination microfractographs, as well as with the variation under irradiation of matrix or fibre/matrix dominated mechanical properties.

AB  - Unidirectional and angle-ply carbon/epoxy laminates were gamma irradiated up to doses of 12 and 20 MGy. Composites with two different, low and high temperature epoxy matrices have been submitted to irradiation and subsequent mechanical testing. The radiation effects were studied by measuring in-plane, interalminar shear and transverse tensile strength, as well as interlaminar strain energy release rate of tested composites. The immersion of composite plate in water at 80 degrees C and mechanical measurements at elevated temperatures emphasized irradiation effects on mechanical properties.
