摘要

The performance of multi-layered ballistic armors consisting of boron carbide front layer, support layers of carbon fibers and ultra-high molecular weight polyethylene (UHMWPE) under the impact of 7.62 × 51 M61 caliber armor-piercing (AP) bullets was investigated by experimental and numerical methods. The boron carbide ceramics used have dimensions of 120 × 120 × 12 mm. The front ceramic layer is supported by hybrid composite structures consisting of 3 K 2/2 twill woven carbon fiber prepreg and Dyneema HB26 prepreg in 0°/90°/0°/90° arrangement. Carbon fibers and UHWMPE were used in three different thicknesses. Composite layers have dimensions of 190 × 175 mm. Ceramic and composite structures were bonded with polyurethane adhesive. The results obtained from the experimental studies were compared with those obtained by the numerical analysis method. Numerical analyses were performed with nonlinear finite element program LS DYNA that includes advanced ballistic models and projectile motion simulations based on digital data. 3D modeling of multi-layered ceramic-composite ballistic armor was performed with the ANSYS/Space Claim module. The quarter axisymmetric model was preferred to save time in the ballistic analysis of armor. As a result of the tests, there was no complete penetration in any of the armors. The ceramic layer caused the bullet to wear. In addition, a mushrooming effect was observed in the bullets. The damage to the armor and bullets was evaluated by comparing the numerical analysis results with those of experimental studies.
