T. Nishiura et al., SYNERGISTIC EFFECTS OF RADIATION AND STRESS ON MECHANICAL-PROPERTIES OF ORGANIC AND COMPOSITE-MATERIALS, Cryogenics, 35(11), 1995, pp. 747-749
Creep tests of epoxy resin and epoxy-based fibre-reinforced plastics (
FRP) in bending during electron-beam irradiation have been carried out
. The purpose of this work was to investigate the synergistic effects
of radiation and stress on the creep behaviour of FRP at cryogenic tem
peratures. These materials showed radiation-enhanced deformation when
subjected to bending stress applied simultaneously. The creep rate inc
reased with increasing stress and radiation-dose rate. This increase w
as more severe in epoxy resin than in FRP. The synergistic effects are
discussed mainly on the basis of temperature dependence.
