“…Further, the study is extended for the two plate thickness of 5 mm and 10 mm to understand the effect of plate thickness. Dewangan and Panigrahi [21] and Chu et al [71] studied the effect of angle of attack on woven composites, and the identical concept is considered here. During ballistic impacts, the contact surfaces of plate and Projectile constantly change on account of the target plate failure.…”

“…This section has discussed the model validation of 2 D plain weave with two different materials. Several researchers [21,34,[36][37][38][77][78][79] investigated the dynamic response of target plates subjected to ballistic impact to understand the various damage mechanisms like fibrillation, fiber splitting and matrix cracking. Similarly, Gu [80] studied the ballistic behaviour of Twaron multilayer fabrics subjected to 7.62 conical-cylindrical steel projectile and mention that the aramid fibers have an insensitivity to the strain rate.…”

“…Further, the study is extended for the two plate thickness of 5 mm and 10 mm to understand the effect of thickness. Additionally, this paper is an up-gradation of the previous works done by the authors for 2 D plain weave [21,58], 3 D angle interlock woven composite [37], and 3 D orthogonal woven composite [38,59]. In the previous studies, only the effects of the target plate are the significant parameter for the study.…”

“…The study revealed that friction is one of the significant parameters for energy absorption, and the fracture in the composite panel is due to the shear plugging. Dewangan and Panigrahi [21] studied the oblique impact on target plates made up of Kevlar/epoxy and comprehended the effect of obliquity for lower and higher velocities. A multi-scale modeling methodology is implemented to study the intricate design and complex ballistic phenomena.…”

The present research deals with the finite element analysis (FEA) considering high strength Kevlar/epoxy composites as a target plate subjected to ballistic impact by varying nose-shaped projectiles. A multi-scale modelling technique has been implemented with FEA to design the intricate weave architecture. The damage properties are adopted using a user-defined function in the explicit analysis. The proposed methodology is validated by the available literature. The conical-shaped projectiles will have more damage and penetration as compared to the flat projectiles, which are studied for two plate thickness. The conical 60° and conical 90° projectiles will have better penetration to the target plate even for the increased thickness, whereas the Conical 120° and Flat projectiles will have a significant reduction in residual velocities. Also, with the increment in thickness, the energy absorption will significantly increase for Flat projectiles as compared to the conical projectiles. For lower velocities, the yarn slippage and puncturing are the major factors of failure along with fiber breakage and matrix cracking. As the velocities increased, the dominant phenomena of failure will be the linear momentum transfer.

“…The weaving structure is one of the factors affecting the bulletproof properties of fiber-reinforced resin matrix composites. At present, plain grain structural materials have been widely used in bulletproof vests [ 14 , 15 , 16 ], bulletproof helmets, and other equipment, but there are problems such as weight, easy delamination, and poor in-plane shear performance [ 17 , 18 ]. With the development of weaving technology, the preparation technology of 3D structural materials is gradually maturing [ 19 , 20 , 21 ].…”

The three-dimensional (3D) shallow cross-bending composite material has many advantages in thickness and in-plane direction, such as high strength, high modulus, inter-layer shear strength, as well as large-area area bearing, energy absorption, etc., which has great application potential in the field of bulletproof armor. To prepare a protective material with both excellent bending performance and good ballistic performance, the effects of weft density and layering method on the bending performance and ballistic performance of three-dimensional ply-to-ply angle interlock (3DPPAI) Kevlar/EP armor materials were studied. The results showed that when the weft density of the material was 33 pieces/cm, its bending performance and ballistic resistance were the best. The 3DPPAI Kevlar/EP armor material prepared by orthogonal layup had more advantages in bending performance, and the unidirectional layup had better anti-ballistic performance. The research results will lay the foundation for structural optimization and engineering applications of such materials.

The multi‐scale modeling and Finite element (FE) analysis of three‐dimensional angle interlock woven composites (3DAIWC) subjected to ballistic impact by conical‐cylindrical projectile have been studied in the present research. A multi‐scale modeling technique has been adopted in the Finite Element Analysis (FEA), which incorporates micro‐meso‐macro‐transition approach called macro‐homogeneous meso‐heterogeneous modeling technique. This macro‐meso‐micro‐transition approach has been implemented in the present research to develop the complex weave architecture of the target plate. A voxel‐based nonconformal mesh has been utilized to understand the behavior of the representative volume element (RVE) of the woven composite target plate. The model is validated by two dimensional weave architecture, which is analyzed for varying nose shapes (30° conical ‐ 180° flat). The macro‐homogeneous results provide the velocity variation and energy absorption of the projectile with respect to the time history.
