“…Ultrahigh molecular weight polyethylene (UHMWPE) fiber is increasingly used in protective structures because it has extremely high specific tensile strength and stiffness [ 1 , 2 ]. With UHMWPE, composite structures can have much lower areal density and much better anti-penetration performance [ 3 ].…”

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.

“…due to their large specific strengths and specific moduli [2,3]. Much research work has been carried out on their failure mechanisms [4] and protective performances [5][6][7]. Attwood et al [8] studied the compressive behavior of the fiber material when loaded along the direction of the reinforcing fibers, and pointed out that the compressive strength of UHMWPE fiberreinforced composite material is not affected by the fibers, but by the micro-bend of the composite sheet.…”

To study the application of ultra-high molecular weight polyethylene fiber (UHMWPE) laminates in light protection field, the ballistic test was used to study the ballistic resistance of UHMWPE fiber materials. In the experiment, 9mm standard bullets were launched by a revolver pistol and 92 type pistol to penetrate the fiber laminates respectively, and the initial velocity of the bullet was recorded by the infrared tachometer. The influence of the areal density, the number of layers, the incident angle and the initial velocity on the protective properties of the fiber laminates were discussed, meanwhile, the microscopic characteristics of the failure mode of the fiber laminates were studied by stereomicroscope. The results show that the areal density and the layer number have obvious influence on the ballistic resistance of the fiber laminates, and the influence of the two materials should be taken into account. In the non-penetrating condition, the total deformation of the fiber laminates is large and the failure of the fiber bundle is the main failure mode. And when penetrated completely, the tensile fracture of fiber laminate material is the main failure mechanism. The study of this paper provides experimental reference for the structural design of UHMWPE fiber laminates.

“…The researchers have been generally focused on the ballistic perforation performance of the plate-shaped alloys up to date [3][4][5][6]. One of the important reasons for this preference is that the production techniques used until the last decade did not allow manufacturing of complex parts.…”

“…AlSi10Mg alloy was chosen as a lattice material, which has high energy absorption ability. Both width and length were chosen as 4 mm for the body-centered lattice structure, while eight different cell height (3,4,5,6,7,8,9 and 15 mm) were used as unit cell parameters. The results show that the ballistic performance of lattice structures could be improved by optimizing the unit cell height for the body-centered lattice structures.…”

Original scientific paperLattice structures, produced by metal additive manufacturing technology, can be a potential alternative in armor applications, which are important parts of defense technologies due to their shock wave damping, energy absorption and light-weight properties. Despite the fact that the protection of metal lattice structures against explosives has been frequently investigated in the literature, their perforation performance is rarely studied. In this research, numerical ballistic penetration tests were carried out with Johnson-Cook strength and failure model parameters by using LS-DYNA software. AlSi10Mg alloy was chosen as a lattice material, which has high energy absorption ability. Both width and length were chosen as 4 mm for the body-centered lattice structure, while eight different cell height (3,4,5,6,7,8,9 and 15 mm) were used as unit cell parameters. The results show that the ballistic performance of lattice structures could be improved by optimizing the unit cell height for the body-centered lattice structures.
