Abstract: When creating glass-metal compounds, including a new structural material of glassmetal composite, the ability of glass to reliably connect with metals at a certain temperature level of glass and metal is used. The adhesion of hot glass is closely related to the physico-chemical processes occurring at the glass–metal interface. The connection depends on the temperature of the metal sheaths and the melt of the glass, the holding time, the pressure, the composition of the glass and metal. In this paper, the influence of technological parameters of centrifugal casting on the strength properties of a structural element of a glass-metal composite is experimentally investigated as a result of the contact interaction of layers, the adhesion strength of which determines the basic mechanical properties of the compound. An experimental method for determining the adhesive force in the study of structural cylindrical samples of glass-metal composite for shear is proposed.

Keywords: thermally stressed state, contact problem, coaxial cylindrical systems, layered composite materials.
