Description
Summary:The influence of radiation damage on the mechanical properties of fiber reinforced plastics (FRPs) has been investigated. Three aspects of our results will be discussed in detail. The first is related to an assessment of the tensile strength and its radiation dependence under the influence of strongly varying radiation conditions; the second to low temperature (~ 5 K) reactor irradiation of selected materials. In this case, identical sets of tensile test samples were transferred into the tensile testing machine, one without warming-up to room temperature and the other after an annealing cycle to room temperature. Finally, a comparison between the radiation response of different materials shows that the tensile properties of a three-dimensionally reinforced bismaleimide degrade least under all irradiation conditions.
