Abstract:
Vehicle chassis, door panels, engine covers, etc. are attacked by bullets, roadside bombs, landmines, and other attacks, which can easily lead to equipment damage and casualties. The reliability and safety of traditional armor protective structure materials are greatly challenged. It is necessary to develop new anti-seismic and bulletproof materials with low density, high protection, small size and easy mounting. Based on the introduction of new lightweight materials such as carbon fiber, ceramics, and non-Newtonian fluids, a multi-material and multi-layer composite armor structure is proposed in this study, which uses the double cutting energy dissipation mode including non-Newtonian fluid cutting and honeycomb element energy absorbing column (bolt). ANSYS autodyn finite element analysis simulation is also used to verify the ballistic performance of the new anti-explosion and bulletproof armor protection structure. This new material can make full use of the advantages of metal, ceramics, fluid materials, and honeycomb nested materials and structures, maximizing its shock wave resistances, projectile/fragment penetration, fire insulation, and heat insulation. The new material has great potential in the battlefield for protecting the equipment and soldiers.
