Various fiber reinforced plastics (epoxies, poly- and bismaleimides as resins; two- and three-dimensional E-, S- or T-glass fabrics as reinforcements) were irradiated at room temperature by 2 MeV electrons and {sup 60}Co-gamma rays up to 1.8 x 10{sup 8} Gy and by different reactor spectra up to a neutron fluence of 1x10{sup 23} m{sup -2} (E>0.1 MeV) at room temperature, 80 K or 5 K. Mechanical tests in the tensile as well as in the intralaminar crack opening (mode I) and in the shear mode (mode II) were carried out on the irradiated samples at 77 K. After low temperature irradiation, half of the samples were subjected to warm-up cycles to room temperature before testing at 77 K. Results on the influence of different radiation sources and annealing cycles on the mechanical properties of all composites will be compared.
