Abstract

In order to obtain the damage characteristics of polytetrafluoroethylene/aluminum (PTFE/Al), five PTFE/Al reactive liners with different Al particle sizes, by mold pressing and sintering, were prepared acting on double spacered plates. The results show that with the increase of Al particle size from 10 μm to 200 μm, the broken hole area, equivalent broken hole diameter, broken hole uplift height and the volume of damaged area of steel and aluminum targets both decrease. When Al particle size is 10 μm, the damaged parameters of steel target are S_steel=0.4 CD (charge diameter), h_steel=0.48 CD, V_steel=420 cm³, and the damaged parameters of aluminum target are S_aluminum=3.82 CD, h_aluminum=1.72 CD, V_aluminum=2280 cm³. PTFE/Al reactive jet with Al particle size 50 nm/70 μm can significantly improve the perforation effect of steel target, and d_steel=0.59 CD. Based on the experimental data, the analysis model of rupturing damage effect of reactive jet on behind‑tagert is obtained by fitting.
