Highly precise space structures are sensitive to vibration during on-orbit operation. This work develops metamaterials that can be integrated into space structures, namely dissipative metamaterial beams for vibration mitigation. The proposed dissipative phononic crystal beam with twisted viscoelastic inclusions presents high structural damping over a large space-level temperature range. The developed novel metamaterials can be implemented in the next-generation space structures, which can be manufactured and assembled in space to enhance their spatiotemporal precision.
