The possibility of using aluminum and its alloys for elements of structural protection
The effectiveness of aluminum is determined by its superiority over steel armor while providing protection against armor-piercing bullets of caliber 12.7 and 14.5 mm, as well as small-caliber projectiles. In addition, aluminum is more technologically advanced, provided with a raw material base, well welded, has a unique anti-mine and anti-fragmentation protection. Most often, modern armor is a laminated aluminum-based board, which includes the front and back layers with an intermediate layer of commercially pure aluminum of 1-3% thickness, installed over the face and under-layers. In this case, the face layer is made of a thickness of 75-90% of the thickness of the plate from the welded alloy with a hardness of at least 165 units. On Brinell, and the back layer - thickness of 5-15% of the thickness of the plate with a hardness of 135-150 HB. At present, the full-scale tests of an aluminum extruded alloy of the FTI DSU design on the basis of AK-8 are carried out, the results of the test for technological shock resistance have shown its compatibility with alloys of the "Tristar" type.
