Опубликована: Ноя. 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.

Herein, a novel material design strategy is proposed: an interpenetrating composite composed of woven orthogonal spiral metal skeleton and polyurethane (PU) elastomer. This combines rigidity flexibility, exhibiting excellent elasticity deformation recovery. The behavior mechanical properties the composites under various loading conditions are investigated through experiments numerical simulations. Different degrees warping behaviors occur in with structural parameters uniaxial tension. Alternating rotations double arrangements can significantly limit phenomenon, maximum reduction 78%. bending load capacity regularly increased by increasing wire diameter decreasing pitch. Increasing number loaded wires enhances composites. Uniaxial compression tests demonstrate that have load‐carrying strain recovery, compressive strength 1.5 times pure PU. Cyclic further illustrate energy consumption stability Overall, introduction skeletons into demonstrates potential to achieve enhanced large recovery simultaneously.
