Abstract
This study investigates the potential of layered ceramo-aluminum sacrificial bumpers as external elements for spacecraft orbital debris shielding. The bumpers are tailored based on the principle of matching shock impedance of ceramic and metallic layers. They consist of aluminum substrate coated from both sides with silicon carbide. The investigation of the bumpers’ performance included both hydrocode modeling and physical hypervelocity impact (HVI) experiments. Obtained results indicate that coated ceramo-aluminum bumpers provide better fragmentation of hypervelocity projectiles and can be considered as a substitute for all-aluminum bumpers in the design of orbital debris shielding.
