Conclusions 1. The best properties were obtained for a composite with silicon carbide, for which the formation energy is low, as for all covalent crystals. It is possible to increase the wetting and adhesion capacity by creating microdefects in the crystal lattice, which breaks the covalent bonds and intensifies s-d electron transfer with the addition of active impurities. 2. Tests of the mechanical properties of various composites showed that they depend on the nature of the component, the amount, and the dispersity of the hardening particles. We determined the composition of the composite material meeting the technological and operational requirements for perforator materials. 3. It was found that the composite based on a cast aluminum alloy is quite soluble in alkali solutions at 100–150°C, which ensures removal of the explosive fragments from boreholes. 4. The combination of high strength, thermal stability, and brittleness makes it possible to recommend the new composite for casings of hollow-charge perforators, thus permitting a broader range of perforation operations and greater depth of boreholes.
