Abstract

The invention relates to an energy-contained shaped charge cover with micro-nano thermite as a material. The shaped charge cover is formed by mixing and pressing raw materials including, by mass percent, 15% to 35% of aluminum powder, 55% to 80% of metallic oxides, 1% to 5% of dicyclopentadienyl iron and 1% to 8% of a binding agent; the binding agent is a fluororubber and polystyrene compound system; and the energy-contained shaped charge cover is high in energy density and high in safety performance, and a reaction cannot be carried out immediately during explosive driving; however, in the penetration process, a strong chemical reaction can start, and extremely-high heat can be sent out, so that a high-temperature incandescence reaction product is generated. The energy-contained shaped charge cover can be combined with a conventional shaped charge cover in a matched manner for use, the effects of properly expanding the diameter of a shooting hole and successively setting on a fire can be achieved, and the damage or killing effect can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of medicine-shaped covers, and relates to a medicine-shaped cover made of thermite energetic materials. The energetic medicine-shaped mask of the present invention not only has extremely high safety characteristics, but also has high energy density, moderate reaction speed and high mechanical properties, and can be applied to the field of high-efficiency damage. Background technique [0002] With the development of modern military technology, various reactive armor protection technologies have been further improved, which poses a severe test to the material selection, structure and manufacturing process of the current armor-piercing ammunition cover. The jet formed by the traditional inert drug cover has insufficient aftereffect after penetrating the target, and cannot strike the enemy target effectively enough. Under this premise, the research on the active drug mask (that is, the energetic drug mask) has ...
