Ceramic Composite Armor

Adhesive is an important part of ceramic-metal composite armor. In order to obtain excellent ballistic performance, some adhesive with a variety of content of nano-SiO2 was prepared, and mechanical properties and ballistic test were conducted. The results show that the pores in adhesive decrease the strength of the adhesive, and the fracture happens along with the pores. To add nano-SiO2 in adhesive can decrease the porosity and the scale of the pores. In the ballistic performance, the adhesive enhance the acoustic impedance, the greater acoustic impedance can increase the energy of transmission wave and decrease the energy of reflection wave, leading to that the ceramic is destroyed slightly. The targets with adhesive added in 20% nano-SiO2 express the best anti-bullet properties. There are so many big blocks left in targets and the height of back convex is only 2.36mm.

This paper mainly focuses on the investigation of dynamic penetration and damage characteristics of a hybrid ceramic composite armor normally impacted by 12.7 mm armor piercing incendiary projectiles. The hybrid ceramic composite armor was composed of a ceramic cylinder layer, a Ti–6Al–4V plate, an ultrahigh molecular weight polyethylene (UHMWPE) composite layer, and an Al alloy panel. Three different areal densities of composite laminates with 82, 87, and 92 kg/m2 were tested. 3D finite element model of the ceramic composite armor was generated in ABAQUS, and the simulation results were employed to study the damage evolution. The effect of alumina ceramic cylinders layer on the ballistic performance and the failure mechanisms of Ti–6Al–4V and UHMWPE after ballistic impact were examined by experimental and simulative results. According to the numerical and analytical models, an optimal thickness range of Al alloy back panel was found in minimizing areal density of the ceramic composite armor.

Abstract In this study, ballistic performances of x wt.-% B4C (x = 5, 10, and 20) reinforced Al5Cu matrix composite samples were investigated as a monolithic and laminated composite armor component. Composite armor plates were produced by the powder metallurgy method. The prepared powders were pressed under 400 MPa pressing pressure. Green compacts were pre-sintered at 400 °C for 30 minutes in order to blow the lubricant. Subsequently, liquid phase sintering was performed at 610 °C for 210 minutes. In ballistic tests, 7.62 mm caliber armor-piercing bullets were used as the ballistic threat. In the ballistic tests of monolithic armors, only 10 mm thick powder metal composite plates were tested. In the ballistic tests of laminated composite armors, these powdered metal plates were layered with 10 mm thick alumina ceramic plate front layers and 10 mm thick AA5083 plates. Although all of the monolithic powder metal composite armors were penetrated, they showed multi-hit capability. All of the laminated composite armors provided full ballistic protection. It was determined that with the increase in B4C reinforcement rate, the ballistic resistance also increased due to the improvement in strength, hardness, and abrasive feature.
