Preparation and Penetration Performance Verification of Low Fluorine Polymer Content Reactive Liner

Abstract To address the combined effect of shaped charge on target penetration performance and post penetration effect, several high-density materials added Al/PTFE reactive liner were designed. Apply the theory of particle size distribution to design the particle size of formula components. And conduct SEM and EDS analysis on the reactive liner made. Static explosion tests were conducted to verify the penetration of several designed formulas into steel targets, and EDS and SEM analyses were conducted on the penetration channels. The experimental results show that the penetration depth of the liner with high-density particles significantly increases, and the addition of copper is more conducive to improving the penetration depth than the addition of tungsten. However, as the amount of tungsten added further increases, the penetration depth shows a downward trend. At the same time, the effects of copper and nickel with similar densities on the performance of the reactive liner were compared, and the results showed that adding copper improved the penetration depth better than adding nickel. This has certain reference value for the design of high-density fluoropolymer based reactive liner.
