Protection Capability of Different Confinement Plates for Rubber Composite Armours against Shaped Charges
Steel is the most used material for the confinement plates of composite armors, but other materials may afford better protection against shaped charges. One of the most interesting materials is ceramic because of its hardness, of its relatively small density and of the reduction of collateral damages, and the other one of the most interesting materials is aluminum because of its small density and ductility. We have therefore compared the protection capability of rubber composite armors built either with copper or with steel. For each configuration, we measured the loss energy of the standard charge shaped jet and the change of the tangential velocity of the different layers with simulation measure and point the deformation of the jet when they penetrated the composite armors. We also have done some X-ray experiments to observe the deformation of the jet to test and verify the result of the simulation. Clear correlations are observed between the projection capability and the confinement materials.
