Abstract Bistable laminates have potential applications in areas such as buffer and soft robotics due to their two stable states ability deform through both snap-through snap-back processes. However, conventional orthotropic bistable with state configurations snap loads are similar magnitude. There is a problem that the deformation cannot be easily driven when laminate stiffness high. To solve this problem, clever design needed reduce load increase so can realized more easily. In paper, we propose method suppress control of by utilizing shape memory 3D-printed polymers (SMP), which enables while reducing driving force. First, numerical model viscoelasticity established study its characteristics, results compared experimental good agreement. The effect SMPs on principal curvature also investigated. Finally, interlayer interface bonding examined microscopic perspective. demonstrate 3D printed effectively enhance laminates, achieving suppression maintaining interlaminar carbon fiber composites. This provides new insights practical significance for active structures.

Analytical Model of Temperature-Induced Deformation for Tunable Thermal Expansion Metamaterial

Materials, Год журнала: 2025, Номер 18(3), С. 532 - 532

Опубликована: Янв. 24, 2025

Tunable thermal expansion metamaterials exhibit superior shock absorption performance in the field of high-precision equipment, but applications are currently restricted by unclear quantitative relationship temperature-induced deformation. Herein, this work leverages virtual principle and deformation geometric to establish a generic control model for bi-materials utilizing key variable coverage ratio under condition no vertical direction. The feasible region regarding flexibility internal serpentine unit lattice structure with different ratios is given. combination finite element experimental methods adopted examine deformation, which presents tunable performances associated temperature. This work, based on established coordination dual-material temperature-sensitive metamaterials, achieves provides reference structural design adaptable various working conditions such as vibration isolation reduction complex engineering aerospace so on. By strategically designing two structures within specified range maintain equivalent flexibility, ultimate reduced one-half due induced temperature variations.
