K. Humer et al., TENSILE-STRENGTH OF FIBER-REINFORCED PLASTICS AT 77-K IRRADIATED BY VARIOUS RADIATION SOURCES, Journal of nuclear materials, 215, 1994, pp. 849-853
The influence of radiation damage on the mechanical properties of fibe
r reinforced plastics (FRPs) has been investigated. Three aspects of o
ur results will be discussed in detail. The first is related to an ass
essment of the tensile strength and its radiation dependence under the
influence of strongly varying radiation conditions; the second to low
temperature (similar to 5 K) reactor irradiation of selected material
s. In this case, identical sets of tensile test samples were transferr
ed into the tensile testing machine, one without warming-up to room te
mperature and the other after an annealing cycle to room temperature.
Finally, a comparison between the radiation response of different mate
rials shows that the tensile properties of a three-dimensionally reinf
orced bismaleimide degrade least under all irradiation conditions.
