Temperature deformation of laminated composite rings


The results of dilatometric measurements on wound circular glass-reinforced plastic rings composed of glass tape and epoxy-phenolic resin are presented. The changes in inside and outside diameter were measured on the temperature interval from 20 to 100°C at various diameter ratios. The theoretical conclusion [1] that anisotropy has a strong influence on the temperature deformation of circular cylinders and rings of composite material is confirmed.
