DETERMINATION OF PROSPECTIVE DIRECTIONS FOR THE IMPROVEMENT OF MATERIALS FOR INDIVIDUAL ARMOR PROTECTION

Abstract

An analysis of world experience in the direction of modern developments of high-strength aluminosilicate glass-crystalline materials, in particular, in the creation of lightweight armor, was carried out. The trends and current state of the glass-ceramics market from 2019 to 2023 have been determined, and an increase in demand for glass-crystalline materials for technical purposes has been established. It was determined that the orientation of the global glass-ceramic market towards fragmentation will allow domestic manufacturers to reduce import dependence and increase the competitiveness of domestic glass-ceramic materials on the world market. The prospect of using high-strength aluminosilicate glass-crystalline materials as a basis for the production of armor protection elements has been established. The criteria for the synthesis of high-strength armored steels have been selected. The choice of oxide systems for the production of protective glass-crystalline materials is substantiated, model glasses are synthesized and the technological parameters of production of impact-resistant sitals, which include cooking, forming, annealing and heat treatment, are determined. Model glasses were synthesized and their structure under thermal treatment conditions was investigated in relation to the physical and chemical properties of the materials based on them. It was established that the developed glass-crystalline materials based on lithium disilicate are characterized by high operational properties and can be used in the creation of modern armor. It was established that the developed high-strength spodumene glass-crystalline materials under the conditions of low-temperature two-stage heat treatment are characterized by high operational properties and can be used as a basis for the development of a composite element of individual armor protection. A comparative assessment of the operational properties and technical and economic indicators of known ceramic and glass-ceramic materials for armor protection made it possible to establish the competitiveness of the developed domestic spodumene-containing materials as elements of individual protection.
