“…The photographs of UHMWPE laminate deformation after the testing are shown in Figure 8, in which the two B 4 C UHMWPE composite armors were fully perforated, and the other three types of ceramic UHMWPE composite armors were partly perforated. There have been extensive studies conducted on the failure modes of UHMWPE laminates, encompassing both the failure modes of UHMWPE laminates themselves 8,30,32,33 and the deformation and damage mechanisms when UHMWPE is utilized as a backing material for ceramic panels 9,12,34,35 . The research findings indicate that UHMWPE laminated composites primarily undergo shear plugging, delamination, plastic deformation (resulting in permanent deflection of the backing plate), transverse shear, and other observable forms of macroscopic damages and failures during impact resistance.…”

Additionally, the fiber bundles within the laminated composites experience tensile deformation, fracture, debonding, as well as pullout and fracture at the rear of the laminated composites.…”

“…The hard-steel core plays the most important role in the penetration process. The failure modes of cores with different properties are different, among which the ductile and low strength cores 11,12 are plastic deformation and erosion, and the failure modes of the core of 12.7 mm API projectile brittle fracture. [13][14][15] The high-strength core material [16][17][18] is made of high-carbon steel after some heat treatment, with a hardness of 62 ± 2RC and a density of 7.85 g/cm 3 .…”

Several commonly used ceramics in ballistic protection were compared in terms of ballistic resistance and failure behavior, including alumina (Al2O3), silicon carbide (SiC), boron carbide (B4C), and silicon nitride (Si3N4). Hybrid ceramic UHMWPE (ultrahigh molecular weight polyethylene) composite armors were impacted by 12.7mm armor piercing incendiary (API) projectiles, with a velocity of around 490m/s. Moreover, there was a layer of aramid fabric composite covering on the impacted side of the ceramic plate. These composite armors were paneled with four different types of ceramics as faceplates and had the same sizes. The ballistic test results show that B4C ceramic provides the worst protection performance, and SiC provides the best protection performance. The angles of ceramic cones formed by different ceramic plates under the same impact load are different, SiC is the widest and Al2O3 is the narrowest. Numerical simulation shows that several ceramic composite targets have the same resistance to the projectile at the pit stage. The fragment mass was quantified by using the screening method, and the results show that the Schumann distribution is more consistent with the experimental results.This article is protected by copyright.

“…The internal ceramic materials of the two hybrid lattices are damaged into cracks after high-speed impact. Under the strain rate of 8.8 × 10 2 /s, the average volume of the ceramic loss of the traditional honeycomb lattice is 65 mm 3 . Under the same train rate, the volume loss of the re-entrant hex auxetic lattice is 17.8 mm 3 (Figure 6j).…”

“…Wilkins first proposed metal-ceramic composite armor and conducted a series of ballistic studies [1]. Afterward, various types of novel metal-ceramic composites were proposed for advanced ballistic protection structure applications, including sandwich structure [2,3], functionally graded structure [4,5], and lateral restraint structure [6]. These novel composites show better ballistic performances than single metal or ceramic constituent materials separately.…”

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.

The finite element model of a 7.62 mm armor‐piercing incendiary bomb penetrating lightweight composite target is established. The structure of the target plate is composed of boron carbide ceramic/carbon fiber laminate/aramid fiber laminate/damping material. The reasonable distribution position of damping material is explored by designing the material structure and geometric parameters. Genetic algorithm is used to optimize the structure of the lightweight composite target plate, and the feasibility of the optimization results is verified through experiments. The results show that under the same surface density, the energy absorption value of the target plate with a certain thickness of back layer damping is 1.36% higher than that of the target plate without damping. And the damping material on the back layer can act as a buffer layer to reduce blunt trauma caused by bullets to the human body. The surface density of the optimized lightweight composite target plate is reduced by 21.6% under the same protection capability. This work provides a theoretical foundation for the impact resistance design and optimization of lightweight composite target plates.Highlights Impact resistance performance of lightweight composite target plate is investigated. The impacting analytical model of the structure is established. The validity of the optimized impacting analytical model is verified by numerical simulation.
