“…Traditional composite protective structures mostly make use of ceramic and metal materials [ 19 , 20 , 21 , 22 , 23 ] and mostly adopt a layered structure (monolithic ceramic as interlayer) or a two-dimensional frame-restraint structure (strip-shaped ceramics as interlayer) [ 24 , 25 , 26 , 27 , 28 ]. The traditional ceramic/metal composite structure tends to have stringent requirements on material performance, which renders poor flexibility in design [ 29 ].…”

The impact response of a composite structure consisting of a metal-packaged ceramic interlayer and an ultra-high molecular weight polyethylene (UHMWPE) laminate has been studied through a ballistic test and numerical simulation. The studied structure exhibits 50% higher anti-penetration performance than the traditional ceramic/metal structure with the same areal density. The metal-packaged ceramic interlayer and the UHMWPE laminate are key components in resisting the penetration. By using a metal frame to impose three-dimensional constraints on ceramic tiles, the metal-packaged ceramic interlayer can limit the crushing of the ceramic and contain the broken ceramic fragment to improve the erosion of the projectile. The large deformation of UHMWPE laminate absorbs a large amount of energy from the projectile. By decreasing the amplitude of the shock wave and changing the distribution of the impact load in the structure, the projectile has longer residence time on the interlayer. The anti-penetration performance shows within 10% variation when the impact position is varied. Due to the asymmetric deformation and high elastic recovery ability of the UHMWPE laminate, the projectile trajectory deflection is increased, and the broken ceramic fragments are restrained, thereby mitigating after-effect damage caused by the projectile after penetrating the structure.

“…Dong et al [14] designed a novel hybrid lattice consisting of a quadrilateral metal lattice and infilled ceramics and analyzed the relation between energy absorption performance indicators and spatial distributions of infilled ceramic constituent materials. Similarly, the penetration resistance of hybrid materials with orthogonal ceramic prisms [15,16] was also studied. Recently, researchers also studied other types of hybrid structures consisting of infilled ceramics and metal lattice frames, such as pyramid lattice [17,18], hexagonal honeycomb lattice [19], and derivative honeycombs [20].…”

In recent years, there have been increasing research interests in investigating the compression and ballistic responses of metal-ceramic hybrid structures, mainly making use of the synergistic effects of conventional metal honeycomb structures and infilled ceramic matrix materials. In this paper, a novel hybrid auxetic re-entrant metal-ceramic lattice is designed and manufactured to overcome the intrinsic conflicts between the strength and toughness of architected mechanical metamaterials, synergistic effects of auxetic re-entrant metal honeycombs and infilled ceramic materials are experimentally and numerically studied, and auxetic deformation features and failure modes are characterized with the digital image correlation (DIC) technique as well. It was found that (1) the infilled ceramic matrix of conventional honeycomb frames only endure longitudinal compression or impact loading along the external loading direction, while auxetic metal re-entrant honeycomb components endure both longitudinal and transverse loading due to the negative Poisson′s ratio effect and (2) the collaborative effects of infilled auxetics and the constraint frames’ hybrid structure dramatically moderate the stress concentration state and improve the impact resistance of single-phase ceramic materials. Our results indicate that the auxetic hybrid design exhibits promising industrial application potentials for blast protection engineering.

“…Ceramic/metal composite armor is used widely in active weapons, such as the armor of the Ukrainian “fortress tank.” In recent years, many scholars have conducted a large number of theoretical studies and tests on ballistic ultimate velocity, projectile hole characteristics, and target plate deformation upon projectile penetration of ceramic/metal composite target plates. 1–5 Ceramics are used widely because of their excellent penetration resistance. Advanced ceramics such as fiber-toughened ceramics, transparent ceramics, and multi-phase ceramics have appeared.…”

The aim of this work was to study the anti-penetration effect of sandwich composite armor with ceramic honeycomb structures filled with aluminum alloy under the impact of high-speed projectiles. The finite element software ABAQUS was used to conduct numerical simulation research on the process of a standard 12.7-mm projectile penetrating sandwich composite armor. The armor-piercing projectile model was simplified as a rigid body. The numerical simulation models were applied to three different sandwich composite armor structures (A, B, and C), each with a total armor thickness of 25 mm. The penetration resistance of the three kinds of composite armor was studied. We obtained velocity curves for the rigid projectile penetrating the different structures. The failure forms and penetration resistance characteristics of the three composite armor structures adopted in this paper were analyzed. In addition, the velocity reduction ratio is proposed as an index to evaluate the penetration resistance performance of the armor. The simulation results revealed decreasing rates of projectile speed in the structures A, B, and C of 69.6%, 91.1%, and 100%, respectively. The third composite armor (structure C) designed here has excellent penetration resistance and can block the penetration of a high-speed (818m/s) rigid projectile. This study can provide some reference for the application of laminated armor material in anti-penetration protection structures.
