Reactive material is a promising new energetic material. In this paper, the damage characteristics of PTFE / Al / W reactive material impacting on double-layer aluminum target are studied by experiments, and the experimental process is simulated by numerical simulation. The experimental results show that when the reactive material impacts the double-layer thin aluminum target, there is almost no reaction when it impacts the first target plate, and the reaction mainly occurs when it impacts the second target plate. Compared with the simulation results, it is proved that the ignition growth model can be used in the simulation calculation of reactive materials.
