1. A tape for damping, the tape comprising:
a first substrate;
a second substrate;
a first layer of viscoelastic damping material at least partially disposed between the first substrate and the second substrate; and
a second layer of viscoelastic damping material wherein the second substrate is at least partially disposed between the first layer of viscoelastic damping material and the second layer of viscoelastic damping material,
wherein the first layer of viscoelastic damping material and the second layer of the viscoelastic damping material, each comprise a first surface and the second surface; and
wherein the first layer of viscoelastic damping material or the second layer of the viscoelastic damping material or both comprise a compositional gradient providing a gradual change in material properties from the first surface of the viscoelastic damping material to the second surface of the viscoelastic damping material.
