Abstract
Provided herein is are multilayer damping laminates comprising alternating damping and constraining layers. The materials and configurations of the damping layers are selected such that the damping layers have a decreasing glass transition temperature profile beginning at the first damping layer, allowing the laminates to effectively dissipate vibrations over a wider range of operating temperatures and/or frequencies. Also provided are systems and methods using the multilayer damping laminates.
