In order to study the impact of inner and outer liner materials on double-layer shaped charge into tandem EFP and penetration power, through experimental study and simulation study, the effect of density of inner and outer layer type, extensibility, strength, melting point on penetration power of EFP was got. The research result shows that penetration can be improved by using materials with low density, good extensibility and low strength for outer layer and low density, good extensibility for inner layer. The experimental results agree with numerical simulation results.
Key words： liner; material; power; simulation
