Dynamic Behavior of Kinetic Projectile Impact on Honeycomb Sandwich Panels and Multi-Layer Plates

In order to study the dynamic response associated with impact of a kinetic projectile on internal structure an artificial satellite, we propose configuration non-metallic material wrapping and multiple damage elements. The satellite is simplified as honeycomb sandwich panel multi-layer plates. We carried out ground test finite element simulation, determined lateral effect penetration performance projectile. Then, studied behavior penetrating using theoretical model. found that its ballistic limit velocity was 150 m/s, deformation opening had little relationship velocity. Finally, impacting plates under various launch parameters. required meet requirements within 325 ± 25 m/s. Projectiles higher initial stronger ability penetrate plates, but velocities than m/s led reduced area. could adapt incident angles less 5° when damaging With increasing angle, reduced, area increased.
