“…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.…”

“…UHMWPE fiber-reinforced resin matrix composite backplate layer is increasingly used in ceramic composite armor. 1,5,[7][8][9] UHMWPE composites with different fabric structures have different protective capacities. Zhang et al 10 have compared three different UHMWPE composites with distinct fabric structures (single-ply 3D orthogonal-woven fabric, 2D plain-woven fabric, and unidirectional prepreg).…”

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.

“…Numerical simulation results show consistency with experimental data. Guo et al [13] investigated the deformation characteristics and failure mechanisms of fiber-reinforced polymer composites backing used in ceramic composite armor under ballistic impact. The results indicated that the failure of the Kevlar-29 panel was dominated by shear plugging in the front layers and fiber tensile breakage in the rear layers while the failure of the UHMWPE panel was dominated by shear plugging initiated from the front layers.…”

In this paper, the ballistic limit velocity of 12.7mm armor-piercing incendiary projectile impacting a typical lightweight ceramic composite armor made of boron carbide ceramic and multi-layered composite materials (carbon fiber/aramid fiber/ultra-high molecular weight polyethylene fiber) was obtained experimentally. The process of impact was numerically simulated by the FEM-SPH method, and the results pointed out the characteristics of the penetration and the energy dissipation rule of each component of the ceramic composite armor. On this basis, the influence of thickness changing of the carbon fiber core layer on the ballistic performance of ceramic composite armor was studied with a typical “sandwich” structure, and the results showed that: when the thickness ratio of ceramic tile to the backing panel is about 1.5, the thickness changing of the carbon fiber core layer has the greatest effect on the ballistic performance. Under this thickness ratio, when the ratio of ceramic tile thickness to bullet diameter is greater than 1, the increase of carbon fiber core layer thickness will cause the ballistic performance index (BPI) of the target to decrease while the ratio is less than 1, the BPI increases or holds at first, and then decreases.

In the current study, an isothermal compression molding process was used to develop enhanced green composites made from alkali‐treated pine nut shell particles (TPS) reinforced in fully bio‐driven benzoxazine (VB) and epoxy (EP) copolymer. Reinforcement with varying weight percent (wt%) of bio‐filler enhanced the properties of composites. Composites showed a rise of 75.9 MPa, 5.8 GPa, and 5.1 kJ/m2 in flexural strength, modulus, and impact strength, respectively. Thermal stability shows that composites can endure higher temperatures and hence be classified as flame‐retardant materials. The dynamic mechanical analysis (DMA) confirms that composites exhibit higher storage modulus, which was elevated to 77.6% compared to the unfilled copolymer. FTIR spectroscopy analyzed the structure of copolymerized composites. Further, finite element analysis (FEA) was observed for the prepared composites. A transversely isotropic composite material model was created with the properties of composites, and stress analysis was observed. FEA outcomes are in good agreement with experimental findings.
