✦ Synopsis

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 temperatures.

These materials showed radiation-enhanced deformation when subjected to bending stress applied simultaneously.

The creep rate increased with increasing stress and radiation-dose rate. This increase was more severe in epoxy resin than in FRP. The synergistic effects are discussed mainly on the basis of temperature dependence.

## Abstract In the oral environment, dental restorative materials are exposed to temperatures ranging from 10° to 50°C. Since the properties of many polymeric materials are sensitive to temperature of this magnitude, it is important to define the effects of service temperature on the mechanical pro
