Abstract

The time-sequenced damage behavior of the reactive projectile impacting double-layer plates is discussed. The analytical model considering the combined effect of kinetic and chemical energy is developed to reveal the damage mechanism. The influences of impact velocity and reactive projectile chemical characteristics on the damage effect are decoupled analyzed based on this model. These analyses indicate that the high energy releasing efficiency and fast reaction propagation velocity of the reactive projectile are conducive to enhancing the damage effect. The experiments with various reactive projectiles impact velocity increasing from 702 to 1385 m/s were conducted to verify this model. The experimental results presented that, the damage hole radius of the rear-plate increases with the increase of impact velocity. At the impact velocity of 1350 m/s, the radius of damage hole formed by PTFE/Al/Bi2O3, PTFE/Al/MoO3, PTFE/Al/Fe2O3 projectile on the rear-plate become smaller in sequence. These results are consistent with the analytical model prediction, demonstrating that this model can predict the damage effect quantitatively. This work is of constructive significance to the application of reactive projectiles.
