Abstract

The necessity of creating innovative protective structures for armoring machinery and equipment is analyzed. A comparative analysis of high-strength materials used for local and individual body armor has been carried out.  The relevance of the development of domestic universal armored materials that combine high strength properties and radio transparency based on lightweight technological magnesium aluminosilicate glass-ceramic materials with high performance properties at the level of world analogues has been determined.  Were formulated the purpose and tasks of the work, which consist in: analysis of the current state of development of glass-ceramic materials for armor protection; development of magnesium-aluminosilicate glass-ceramic materials with high armor resistance, impact resistance and radio transparency; investigation of the operational properties of the developed glass-ceramic materials and their armor resistance; assessment of the competitiveness of the developed glass-ceramic materials. A set of requirements for a glass matrix for obtaining protective glass-ceramic materials has been formulated. Compositions and technological parameters for the production of glass-ceramic materials under the conditions of two-stage low-temperature heat treatment have been developed. The study of the electrical properties of experimental glass-ceramic materials made it possible to establish the possibility of effective functioning of on-board wireless communication systems when using the developed materials as elements of armor protection. It was found that the developed glass-ceramic materials are characterized by high operational properties (KCU = 5.8 kJ/m2; HV = 10.4 GPa; K1C = 8.5 MPa∙m1/2) and armor resistance STANAG 4569 (level 2). The competitiveness of the developed glass-ceramic materials based on mullite is analyzed. It has been established that a significant increase in fracture toughness and a decrease in the density of the developed material when comparing properties with a similar armor element (corundum-based plate) will significantly reduce the weight of the armor elements by ≈1.4 times and its cost by five times, while maintaining its protective properties.

装甲防护用通用高强度镁铝硅酸盐玻璃陶瓷材料的研制
分析了创新装甲机械设备防护结构的必要性。对用于局部和单兵防弹衣的高强度材料进行了对比分析。基于轻量化技术的镁铝硅酸盐玻璃陶瓷材料的高强度性能和无线电透明度相结合的国内通用装甲材料的发展具有世界类似物水平的高性能,已经确定了相关性。明确了本工作的目的和任务,主要包括:分析装甲防护用玻璃陶瓷材料的发展现状;高抗装甲、抗冲击和无线电透明度的镁铝硅酸盐玻璃陶瓷材料的研制研制的玻璃陶瓷材料的作战性能及抗装甲性能研究新型微晶玻璃材料竞争力评价。制定了一套用于获得保护性玻璃陶瓷材料的玻璃基体的要求。研究了在两段低温热处理条件下生产玻璃陶瓷材料的成分和工艺参数。通过对实验玻璃陶瓷材料电学性能的研究,可以确定将开发的材料作为装甲保护元件时,机载无线通信系统有效运行的可能性。结果表明,所制得的玻璃陶瓷材料具有较高的操作性能(KCU = 5.8 kJ/m2;HV = 10.4 GPa;K1C = 8.5 MPa∙m1/2),抗装甲性能STANAG 4569(2级)。分析了莫来石基玻璃陶瓷材料的竞争力。研究表明,与同类装甲元件(刚玉基板)的性能相比,该材料的断裂韧性显著提高,密度显著降低,在保持其防护性能的同时,装甲元件的重量将显著降低约1.4倍,成本将显著降低5倍。
