Abstract (en)
[origin: WO9604491A1] The present invention provides a method of improving the vibrational damping characteristics of a structural material and the articles (1, 4) formed therefrom. The method involves: forming a cavity (2, 5) within the structural material at a point where at least one vibrational mode is active; and placing a nonconstrained vibration damping material (3, 6) into the cavity, wherein the vibration damping material comprises a viscoelastic material and preferably an effective amount of a fibrous material.
