The optimal pouring conditions provide the lowest value of the peak acceleration of a falling body (248.76 m/s2), which indicates the ability of the material to effectively dissipate the impact energy. In addition, the time of the vertical acceleration of the combat vehicle mock-up increases, which indicates the effective dissipation of the dynamic load of the explosion and confirms its improved damping properties. The absence of destruction of the composite material plate after exposure to an explosive load indicates the formation of a strong contact between the phases and the absence of structural defects. The resulting composite has significant advantages under shock and blast loading. The maximum vertical acceleration of the composite (974.56 m/s2) is 18.45% less than that of aluminum (1195.31 m/s2), which demonstrates a better ability to absorb explosion energy. The average deflection of the composite after dynamic loading decreased by 14.5% compared to the base, which demonstrates the high elastic-plastic characteristics of the composit The obtained results confirm the effectiveness of the developed technology for creating materials with high performance characteristics that have the prospect of being used in protective structures, in particular in mine screens and other areas requiring increased impact resistance. The proposed technology for manufacturing the composite is environmentally friendly, as it involves the use of metal-cutting machine waste, which reduces the cost of raw materials and helps reduce industrial waste. A technological instruction for the manufacture of the composite has been developed, which ensures high efficiency of impact energy absorption, rational use of resources, and environmental safety of production.  Product Description popup.authors Bisyk Serhii P.
