Abstract
The temperature–deformation–time dependences of the physical and mechanical characteristics of polymer glass based on polymethylmethacrylate necessary for the strength calculation of glazing were experimentally determined. The calculation of the residual and temperature stresses in a glazing element made of VOS-2 heat-resistant copolymer glass was performed. Ways to decrease the stresses that occur under operation by developing materials with decreased values of the elastic modulus and the temperature coefficient of linear expansion were proposed. The work was performed within complex research trend 15.4 [1] Optical Materials and Glazing Materials (“Strategic Trend of Development of Materials and Technologies for Their Processing for the Period to 2030”).
