Investigation of the mechanical properties of polymer composite materials with various types of hybrid matrices in the extreme conditions of the Arctic

Abstract

The technology of manufacturing carbon plastics samples with various types of hybrid matrices is presented, one of the components of which is completely cured, and the second (technical wax, anaerobic and organosilicon polymer materials) retains its viscoelastic state after forming products, which ensures a change in the mechanical properties of structural materials. The possibility of using carbon plastics with various types of hybrid matrices for the manufacturing of mechanical engineering products that are used in extreme Arctic conditions is studied. A method for conducting mechanical tests to determine the tensile strength of carbon plastics samples with various types of hybrid matrices at temperatures t1 = 20 ± 2°C, t2 = −30°C, t3= −50°C. The results of changes in the strength and deformation properties of carbon plastics with different types of hybrid matrices at negative and positive temperatures compared to the values of the same indicators of carbon plastics without viscoelastic components in the matrix are presented and analyzed.
