“…Other types of non-oxide ceramic materials are carbides (e.g., silicon carbide-SiC and boron carbide-B4C) nitrides (e.g., silicon nitride-SiN) and borides (e.g., titanium diboride-TiB2). Enumerated non-oxide ceramics are more expensive than aluminum and a combination of different non-oxide ceramics is also possible [11][12][13].…”

In recent decades, the expansion of arms development has initiated the need to increase the protection of people and vehicles from pistol and rifle ammunition. Modern ceramic and ceramic-based materials are lightweight and durable and provide a sufficient level of protection against the penetration and impact of ammunition, which can protect the vital organs of the person. Modern tendencies require the addition of armor to vehicles, which reduces the necessity of excessive bulk steel usage and eliminates large and heavy mass weight amounts. By replacing the armored steel with new ballistic materials, a higher level of ballistic protection could be achieved, as well as reduction of weight, which both allows better mobility and increases the ability of installment of additional battle fighting equipment. Modern ceramic materials used in the production of armor are made by sintering the ceramic powder under certain conditions in a suitable molding tool. The chapter will cover the short material requirements, and material responses to ballistic impact, production methods, and applications. Also, the chapter will include the usage of ceramic fibers, alumina, silicon and boron carbide, titanium diboride, and ballistic materials that consist of a ceramic face bonded to a reinforced plastic laminate or metallic backplate.

“…Керамика Al 2 O 3 −SiC широко используется в промышленности в качестве износостойких пар трения, режущего инструмента, элементов керамической защиты и др. [1][2][3]. Частицы SiC позволяют повысить механические свойства оксида алюминия за счет торможения миграции границ зерен и формирования сжимающих внутренних полей напряжений, изменяющих характер разрушения керамики [4][5][6][7][8][9].…”

The features of spark plasma sintering of submicron Al2O3 powders with different contents (0, 0.5, 1.5, 5 vol.%) of -SiC nanoparticles have been studied. The microstructure and hardness of Al2O3 + 5 vol.% SiC ceramics obtained by sintering Al2O3 powders with -SiC particles of various types (nanoparticles, submicron particles, fibers) have been studied. Sintering was carried out at heating rates (Vh) from 10 to 700 °C/min. The sintering process of Al2O3 + SiC ceramics with low heating rates (Vh = 10–50 °C/min) has a complex three-stage character, with a flat area in the temperature range of 1200–1300 °C. At high heating rates (Vh > 250 °C /min), the usual three-stage character of sintering is observed. The analysis of temperature dependences of compaction was carried out using the Young-Cutler model; It was found that the kinetics of powder sintering is limited by the intensity of grain boundary diffusion. It is shown that the dependence of the hardness of Al2O3 + SiC ceramics on Vh has a nonmonotonic character, with a maximum. In the case of pure alumina, an increase in Vh leads to a monotonic decrease in hardness.

“…At a later stage, instead of monolithic metal armors, ceramic/metal armors were proposed to meet these requirements. These ceramic/metal armors are composed of ceramic on the strike face, with higher strength under compression than when under tension, and the metal is on the back, offsetting the drawbacks of ceramics [ 3 ]. The mechanism of ceramic/metal armors in protecting from projectile impact is that ceramics reduce the penetration ability of projectiles by deforming and eroding the projectile, then the backplate absorbs the residual kinetic energy [ 4 , 5 , 6 ].…”

Although polyurea has attracted extensive attention in impact mitigation due to its protective characteristics during intensive loading, the ballistic performance of polyurea-reinforced ceramic/metal armor remains unclear. In the present study, polyurea-reinforced ceramic/metal armor with different structures was designed, including three types of coating positions of the polyurea. The ballistic tests were conducted with a ballistic gun; the samples were subjected to a tungsten projectile formed into a cylinder 8 mm in diameter and 30 mm in length, and the deformation process of the tested targets was recorded with a high-speed camera. The ballistic performance of the polyurea-reinforced ceramic/metal armor was evaluated according to mass efficiency. The damaged targets were investigated in order to determine the failure patterns and the mechanisms of interaction between the projectile and the target. A scanning electron microscope (SEM) was used to observe the microstructure of polyurea and to understand its failure mechanisms. The results showed that the mass efficiency of the polyurea-coated armor was 89% higher than that of ceramic/metal armor, which implies that polyurea-coated ceramic armor achieved higher ballistic performance with lighter mass quality than that of ceramic/metal armor. The improvement of ballistic performance was due to the energy absorbed by polyurea during glass transition. These results are promising regarding further applications of polyurea-reinforced ceramic/metal armor.
