摘要： Vibration damping viscoelastic damping material laminates are described. The tapes generally include at least two viscoelastic damping material layers and at least one substrate. The tapes may optionally include one or more release liners. Also described are constrained layer systems formed by adhering the tape to a first substrate and/or second substrate undergoing vibration.

摘要： Provided herein are multilayer tape constructions comprising a damping layer and a bonding layer, wherein the multilayer tape construction effectively dissipates vibrations at low temperatures. The materials and configurations of the layers are selected such that the glass transition temperature of the bonding layer is greater than the glass transition of the damping layer, and the difference between the glass transition temperatures is related to the relative thicknesses of the damping layer and the bonding layer. The multilayer tape constructions may further comprise a carrier layer. Also provided are systems and methods using the disclosed multilayer tape constructions.
