To counter thin Dining Tables and lightweight targets such as drone swarms, a specialized design of 7.62 mm energetic bullets has been developed.These bullets utilize reactive materials as the core encased in a copper jacket, offering the advantages of impact-induced energy release, multiple damage, and lightweight.

The study involved the preparation of three energetic bullets using the reactive materials (different ratio of PTFE-Mg-Bi2O3 and PTFE-Mg-Bi2O3-W) and systematically evaluating their destructive effect.The results showed that three energetic bullets (EB-A, EB-B, and EB-W) successfully penetrated two-layer stacked 2 mm 50# cold-rolled steel targets, and the respective reaction durations observed during the penetration process were 4.1, 3.

5, and 9.2 ms.After armor-piercing, energetic bullets released an amount of chemical energy and produced fragmentation, deflagration INSTANT ENERGY B12 reactions, and overpressure destructive effects.

To further investigate the damage mechanism of the three reactive material-filled bullets, a detailed analysis of PTFE-Mg-based reactive material, such as reaction energy, burning rate, combustion temperature field, reaction overpressure, was conducted.Our work provides a comprehensive understanding of energy release performance of the reactive materials and damage behavior of the energetic bullets.
