THERMAL EXPANSION OF PHOTOELASTIC MATERIALS

Abstract

A quartz thermal expansion apparatus was developed to measure the thermal expansion of photoviscoelastic plastics. Three different methods of motion measurement correlated with a maximum error of ! 1 per cent using three different models of Hysol 4290 epoxy. The thermal expansion of a 30 per cent plasticized epoxy was determined and was found to exhibit essentially the same characteristics as the 4290 epoxy except for a shift in the temperature scale. Both sets of data are similar to rocket grain behavior. (Author)
