摘　　要：为研究航天器蜂窝夹层结构的超高速撞击防护性能,采用轻质多孔火山岩弹丸模拟微流星体,进行超高速撞击试验,研究蜂窝夹层板的损伤特性。结果表明:采用硅橡胶垫片,结合弹托使用,可实现轻质、脆性火山岩弹丸的超高速完整发射;在火山岩弹丸超高速撞击条件下,蜂窝夹层板主要发生正面蒙皮穿孔、蜂窝芯层坍塌、背面蒙皮花瓣开裂、脱胶等损伤模式;正面蒙皮穿孔直径随弹丸直径的增大而增大;蜂窝芯层坍塌面积和背面蒙皮损伤面积不仅与冲击能量、弹丸直径相关,还与冲击位置相关。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.
