摘要：
In order to investigate the hypervelocity impact performance of honeycomb sandwich structures in spacecrafts, lightweight porous volcano rock projectiles were used to identify the micro-meteoroids, and hypervelocity impact tests were conducted to investigate the damage characteristics of honeycomb sandwich panels. The results show that the lightweight brittle volcano rock projectiles could be completely lunched by using a sabot with a silicon rubber pad. Following hypervelocity impact of volcano rock projectiles, the damage modes of honeycomb sandwich panels mainly took the forms of front surface perforation, honeycomb collapse, rear surface petalling and debonding, etc. The perforation diameter of the front surface increased with the diameter of the projectile, while the collapse area of the honeycomb and the failure area of rear surface were influenced not only by the impact energy and projectile diameter, but also by the impact position. © 2018, Editorial Office of Journal of Vibration and Shock.
