“…The tensile and compressive forces from the impact of the projectile are intensive enough to make the ramie fibers deform and even break. The presence of brittle composite matrices such as epoxy resins can increase energy or absorb traces in ballistics [32].…”

Multilayer armour system (MAS) becomes the best choice in reinforcing protection for military officers against projectile attack which has a high velocity of up to 7.62×51 mm NATO ball lead core (projectile level III NIJ standard) or AP 7.62×51 mm hard steel core (projectile level IV NIJ standard). This study aimed to analyze the damage formation of wolfram carbide (WC) ceramic and ramie fiber composites. The frontmost MAS uses WC ceramic and is enveloped by a back layer of ramie fiber composites with epoxy resin reinforcing material as the matrix. Ballistic testing was carried out in this study using a long-barreled rifle to determine the resistance of the MAS from projectile impact. The speed meter in ballistic testing uses a velocity sensor type light screen B 471 and clay witness is used to measure back face signature (BFS). The results show that 7.62 lead core and hard steel core projectiles were unable to penetrate the 3-layer ceramic MAS in the front. The results are marked by a relatively low BFS value of 1.45 and 1.17 mm, so that the energy in the MAS with 3 ceramic layer is absorbed efficiently but with the phenomenon of rupture ceramic failure. Ceramic rupture failure needs to be overcome by bonding several layers of ramie so that MAS can be used in the next stage. MAS with 1 and 2 ceramic layers are unable to withstand projectile level III and level IV NIJ standard. From these results it is known that the MAS limit can withstand the projectile level III and IV NIJ standard, namely MAS with 3 ceramic layers. The damage formation of ceramic was rupturing ceramic failure. Therefore, it is necessary to design a ceramic binder by placing some ramie fibers in front of the ceramic

“…The compressive stress of the ZrO 2 ceramic tip was different from that of the metal tip during the impact on the ceramic panel [13,14]. The ceramic composite projectile penetrated the ceramic composite armor in two parts, namely, the penetration by the ZrO 2 ceramic tip and the penetration by the metal core.…”

“…In view of the technical challenges faced by the penetration of conventional ammunition on ceramic armor, such as serious bullet abrasions, relatively high KE loss, and a significant reduction in penetrative effectiveness [6][7][8][9], novel research into penetrative materials has been performed both domestically in China and worldwide. Examples include the impact of ceramic rods and polycrystalline diamond on protected targets [10][11][12], the penetrative effect of ceramic-metal composite projectiles on protected targets [13][14][15], and the impact of Al 2 O 3 ceramic balls on ceramic composite armor [16]. In particular, research into the penetrative effect of metal rod-ZrO 2 ceramic ball composites on protected targets is prominent [17], which can cause a large area of damage to the ceramic layer of the ceramic composite armor.…”

Exploring new armor-piercing materials is crucial for improving the penetrative ability of projectiles. Based on the process of in situ solidification injection molding through ceramic dispersant hydrolytic degradation, a ZrO2 ceramic material suitable for use as the tip of a 12.7 mm kinetic energy (KE) projectile was prepared. The ZrO2 ceramic tip can be matched with the metal core of a conventional projectile to form a ceramic composite projectile, increasing the damage to the Al2O3 ceramic composite armor. Specifically, the ZrO2 ceramic tip can increase the impact load on the Al2O3 ceramic panel, prolonging the pre-damage phase and reducing the stable penetration phase, shortening the mass erosion time of the metal core compared with a 12.7 mm metal KE projectile tip. The ceramic composite projectile with the ZrO2 ceramic tip has a lower critical penetration velocity than a 12.7 mm metal KE projectile for Al2O3 ceramic composite armor. Furthermore, the residual velocity, residual length, and residual mass of the metal core of the ceramic composite projectile that penetrated the Al2O3 ceramic composite armor are greater than those of a 12.7 mm metal KE projectile.

“…Two, it is becoming easy to defeat strong steel via armour piecing (AP) projectile that causes a major setback for conventional steel. Understanding this weakness, ammunition designers are replacing standard metallic projectile nose with toughened-ceramic nose in an attempt to increase projectile penetration capability in protection targets [1]. These led to search for high-performance but lightweight and low-cost protective materials (for personnel and vehicles) to improve manoeuvrability, survivability and reduce injury when subject to threats including blast [2,3].…”

“…Consequently, ceramic-steel composites have been introduced to offer the solution for efficient lightweight armours [5][6][7][8][9][10]. Precisely, low density, high hardness, high rigidity and compression strength of ceramics [1,5] makes it popular and suitable for armour systems; including aircraft structures, personal armour and military vehicles [11][12][13][14][15]. Several ceramic materials are used for facial ballistic armours: alumina [16][17][18], boron carbide (B4C) [19], silicon carbide (SiC) [20].…”

The Terminal ballistics is the study of science that deals with the interaction involved in two impacting bodies. This research focused on the high-impact resistance of layered composite comprising of alumina ceramic and armour steel. The composite was designed to have ceramic as the facial plate with armour steel as its backing plate. For the numerical study, the ceramic thickness was varied (6, 8, 10, 12 mm) while keeping the thickness of backing steel constant (7 mm). The projectile, 7.62 mm armour-piercing (AP), was set with a velocity of 838 m/s and made to impact the different ceramic–steel composite target configurations at zero obliquity. The study captured fracture processes of the ceramic, the deformation of projectile, and backing steel. An effective optimum thickness ratio of 1.4 (ceramic:steel; 10/7) for the ceramic/steel components with less deformation of the backing steel is found. Thereafter, the result of the numerical study was validated by experimental ballistic investigation of the determined optimum ceramic/steel ratio. The experiment corroborated the simulation results as the alumina ceramic provided efficient protection to armour steel component after a severe interaction with the impacting projectile.
