The present research involves studies of the influence of the physico-mechanical properties of the ceramics on the ballistic resistance of the new concept of the hybrid, ceramic–multi-layered UHMWPE composite armour developed using SiC and Al₂O₃ ceramics differing in thickness. Ballistic verification of new design of the ballistic composite armour was conducted in the scope of the protection against more than one shot (multi-hit) using 7.62 × 39 mm MSC and 5.56 × 45 mm SS109 ammunition. Tests of physico-mechanical properties, covering the determination of density, acoustic impedance, Young’s modulus, hardness, and resistance to brittle fracture, were conducted for the ceramic materials. Obtained results show that the ballistic behaviour of the testing system based on ceramic tiles being made of the same materials (SiC or Al₂O₃) of the different thicknesses does not directly correlate with the hardness, brittle fracturing, or Young’s modulus of ceramics. For ceramic plates of the same thickness being made of different materials in chemical terms, performed studies have shown that the ballistic resistance of the testing system does not only depend on acoustic impedance of ceramic plates, which should be as similar as possible to the acoustic impedance of the backing material in the ballistic armour, but also the resistance to brittle fracturing K_1c is an important parameter of the ceramic plates entering the composition of the armour, and it should be as high as possible. Only the combination of these two properties yields the best ballistic protection of the armour when testing using the multi-hit procedure with the use of 7.62 × 39 mm MSC and 5.56 × 45 mm SS 109 ammunition.

本研究涉及陶瓷的物理机械性能对使用SiC和Al ₂ O ₃研制的混合陶瓷多层UHMWPE复合装甲新概念的弹道阻力的影响的研究。厚度不同的陶瓷。在使用7.62×39毫米MSC和5.56×45毫米SS109弹药的一次以上射击（多次打击）的保护范围内，进行了防弹复合装甲新设计的弹道验证。对陶瓷材料进行了物理机械性能测试，包括密度，声阻抗，杨氏模量，硬度和抗脆性断裂的测定。所得结果表明，由相同材料（SiC或Al ₂ O _3）制成的瓷砖测试系统的弹道性能）的不同厚度与陶瓷的硬度，脆性断裂或杨氏模量没有直接关系。对于化学上用不同材料制成的相同厚度的陶瓷板，进行的研究表明，测试系统的弹道阻力不仅取决于陶瓷板的声阻抗，而且应与声阻抗尽可能相似弹道装甲中的背衬材料，还具有抗脆裂性K _1c是陶瓷板进入铠装组成的重要参数，并且应尽可能高。当使用7.62×39 mm MSC和5.56×45 mm SS 109弹药进行多次打击程序进行测试时，只有这两种性能的组合才能对装甲产生最佳的防弹保护。
