Structural Design of Multi-component Material for Passive Protection against Explosion and Bulletproof with Double Cutting Energy Dissipation
Vehicle chassis,door panels,engine covers,etc.are attacked by bullets,roadside bombs,landmines,and other at-tacks,which can easily lead to equipment damage and casualties.The reliability and safety of traditional armor protective struc-ture 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-explo-sion 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 penetra-tion,fire insulation,and heat insulation.The new material has great potential in the battlefield for protecting the equipment and soldiers.
