**5. Conclusions**

In this paper, the X-ray photography experiment of reactive shaped charge jet formation was performed on PTFE/Al liners prepared with two aluminum particle sizes (5 μm and 100 μm). The secondary development technology was used to simulate the formation of PTFE/Al reactive shaped charge jets and compared with the experimental results. By analyzing the experimental phenomenon and simulation results, the following conclusions were obtained:


(3) The effect of Al particle size on the mechanical properties and reaction rate of PTFE/Al RMs are the main reason for the formation of the difference during the jet formation. Compared with the 5 μm aluminum powder, the PTFE/Al reactive liner prepared with 100 μm aluminum powder reacted slowly and the morphology of jet is more condensed, which is conducive to generating greater penetration depth.
