Monodomain Liquid‐Crystal Elastomer Lattices for Broad Strain‐Rate Mechanical Damping

Advanced Engineering Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 7, 2024

Designing structures that effectively dissipate energy across a broad range of mechanical loading rates, including those from compression, shock, and vibration, poses significant engineering challenge. In this study, liquid‐crystal elastomers (LCEs), which possess anisotropic properties due to the alignment their polymer backbone, are explored. As result, LCEs exhibit soft elastic response under loading, making them ideal for dissipation. Advances in additive manufacturing (AM) enable simple fabrication foamlike dissipative with complex lattice geometries. Herein, direct ink write 3D printing, an extrusion AM method, is used fabricate aligned, monodomain LCE strain‐rate damping. work, it shown these can strain quasi‐static environments, comparable traditional elastomeric lattices, provide improved damping high drop testing elasticity. Additionally, dynamic lattices enhance at structural natural frequencies high‐frequency attenuation. findings, promising method presented fabricating devices rates.
