Can vacuum-packed structured fabrics control vibrations? This paper presents an initial survey of the vibration response of beam-like specimens created from a vacuum plastic bag encompassing single- or double-layer 3D-printed structured fabrics. The study examines the bending stiffness and energy dissipation properties in relation to vacuum levels and fabric configurations. Quasi-static analysis of bending stiffness and energy dissipation is performed. Comprehensive overview of dynamic properties with measurements of dynamic stiffness frequency response function and hysteresis loops at three frequencies (below, at, and above the fundamental bending resonance frequency). Bending stiffness and resonance frequency can be tuned with vacuum levels. Cubic mails exhibit the highest bending stiffness. Double-layer mails show much higher bending stiffness. The study suggests that increasing the vacuum level suitably varies bending stiffness and resonance frequency. However, the vacuum level minimally affects energy loss, suggesting that material energy dissipation within the unit particles is the primary damping mechanism once the fabric jams. Cubic mails show highest bending stiffness while double layer mails also improve bending stiffness.
