Tensile and Shear Fracture Behavior of Fiber Reinforced Plastics at 77k Irradiated by Various Radiation Sources

  • Chapter
Book cover Advances in Cryogenic Engineering Materials

Abstract

The influence of radiation damage (gamma and neutrons) on the mechanical properties of fiber reinforced plastics (FRPs) has been investigated. Different types of FRPs (two or three dimensional E-, S- or T-glass fiber reinforcement, epoxy or bismaleimide resin) have been irradiated at room temperature with 2 MeV electrons and 60Co γ—rays up to 1.8×108 Gy as well as with different reactor spectra up to a fast neutron fluence of 5×1022m−2(E > 0.1 MeV). Tensile and intralaminar shear tests were carried out on the irradiated samples at 77 K. Some samples were irradiated at 5 K and tested at 77 K with and without an annealing cycle to room temperature. The results on the influence of these radiation conditions and of the warm-up cycles on the mechanical properties of all FRPs are compared and discussed.
