✦ Synopsis
Different types of fibre reinforced plastics (two-or three-dimensional E-, S-or T-glass fibre reinforcement/epoxy, bismaleimide or polyimide resin) were irradiated at room temperature by 2-MeV electrons and 6oCo-gamma rays up to 1.8 x IO* Gy and by different gamma and neutron fission spectra up to 1 x 10z3 m-*, respectively. Mechanical tests in the tensile as well as in the crack opening mode (mode I) and the intralaminar shear mode (mode II) were carried out on the irradiated samples at 77 K. After irradiation at 5 or 80 K, half of the samples were subjected to warm-up cycles at room temperature before testing at 77 K.
