基于陶瓷化铝板设计了单层防护屏结构和双层防护屏结构，利用二级轻气炮对其进行高速撞击实验。用于模拟空间碎片的2017铝球弹丸直径分别为3．97 mm 和6．35 mm，撞击速度为1．64～4．96 km／s。分析了铝板表面陶瓷层对防护结构高速撞击损伤及防护性能的影响。结果表明：防护屏表面的陶瓷层可使单层防护屏结构抵御更大速度范围的粒子撞击；以表面陶瓷化铝板为首层防护屏的铝网填充式防护结构有助于撞击粒子的首次破碎以及次生碎片的撞击动能吸收。

The ceramic coating shields with single bumper and dual-wall bumper were designed taking advantage of the improvement on Al-Whipple shield.A series of high-velocity impact tests were practiced with a two-stage light gas gun facility.The diameters of projectiles used to simulate the space debris were 3.97mm and 6.35mm respectively.The impact velocities of Al-sphere were varied between 1.64km /s and 4.96km /s.The effects of ceramic coating on the damage and protection performance of shield were analyzed.The results indicate that the ceramic coating on the surface of bumper broadens the impact velocity spectrum,so that the single-wall bumper shield can withstand higher velocity impact. The Al-mesh stuffed shield with the ceramic coating surface used as a first layer of bumper can help the primary fragment of projectile and the subsequent absorption of kinetic energy of debris cloud.
