“…The load distribution of the ceramic tiles during the anti-penetration process changes due to the UHMWPE laminate, which results in a wider range of circumferential cracks on the top of the fracture cone than the reference target without UHMWPE laminate, as shown in Figure 14 . Larger circumferential cracks can not only increase the absorbed projectile energy by expanding the crushing range of the ceramic tiles but also prolong the residence time of the projectile on the ceramic surface [ 39 ], which explains that the ceramic tiles in the T-X developed penetrating damage later, as shown in Figure 13 .…”

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.

“…The composite target was fixed in a steel frame with a covering plate, with an exposed area of 150 mm × 150 mm. Studies 21,[25][26][27] have shown that lateral constraint and prestress had an important effect on the performance of ballistic ceramics. In order to avoid the interference of above factors on the test results, as shown in Figure 4A, there was an above 3 mm gap between the ceramic side surface and the inner wall of the steel frame, which was filled with expandable polyethylene.…”

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.

“…As this point it is also worth to note that under high stress level ceramics may change their fracture character to a more ductile fashion which is the general idea behind modeling them with viscosity-embedded constitutive formalism [36,37]. In particular, beyond a compressive pressure limit, armor ceramics posses a ductile behivour which definitely enhances their energy absorbing limit up to fracture which could also be termed as confinement-induced brittle to ductile transition [38]. High caliber ammunition can impact the target at a speed of approximately 900-1000 m s −1 .…”

A ceramic/composite add-on armour system with innovative ceramic geometry (cylindrical) against 14.5×114 mm API/B32 projectile was developed and ballistic performance of the armour was investigated both experimentally and numerically. Numerical analysis was used to calculate exit velocities of the projectile after passing through the ceramic/composite layer (before penetrating the Armox 500T which simulates hull structure of an armoured vehicle) and also contributed to the selection of optimum ceramic thickness. The calculated projectile velocity-time curves (from numerical analysis) for three different ceramic thicknesses are given comparatively in the study. The curve characteristics are the same for three different analyses. The duration of the total absorption of the projectile energy is about 0.2 microseconds (ms). There were differences in the transmission of the stress wave and the delamination in the Ultra-High-Molecular-Weight Polyethylene (UHMWPE) layers differed as ceramic thickness increases. The separation between the layers varied with the change in projectile energy. As a result of the ballistic test, the armour prevented 14.5×114 mm API/B32 ammunition with desired damage mechanisms. In the x-ray image taken after the shootings, it was seen that the ceramic damage was local which enhanced multi-hit resistance capability and the geometry of the cylindrical alumina played an important role in the localization of the ceramic zone damage during the projectile penetration process. Due to this cylindrical ceramic geometry, the projectile moving on after the moment of impact constantly encounters a curved and new surface, and thus it is deflected and exposed to more wear. The areal density of the armour was also reduced by using the UHMWPE (which is one of the composite material whose fibres have the lowest density and good mechanical properties) composite plate as the backing plate.
