Abstract

Various GFRP laminates (two dimensional S-glass fiber reinforcements, epoxies or bismaleimide resins) have been irradiated with 2 MeV electrons at ambient temperature and with different reactor spectra at ambient temperature and at 5 K up to dose levels of about 270 MGy prior to short-beam-shear (SBS) testing at 77 K. After low temperature irradiation, half of the samples were subjected to an annealing cycle to room temperature before testing at 77 K. Results on the influence of different radiation sources, irradiation temperatures and annealing cycles on the interlaminar shear strength (ILSS) of the laminates are compared and discussed.
