Abstract
A coating composition and method are disclosed for reducing vibration and noise when applied to a structure such as in transportation and industrial equipment systems. The coating composition of the present invention includes a viscoelastic material with discrete stiff fibers suspended therewithin. The viscoelastic material is preferably selected from acrylics, silicones and polyurethanes, and the discrete fibers are preferably carbon fibers. The manipulation of the fiber volume fraction within the viscoelastic material, the dimension of the fibers, the orientation of the fibers within the composition and the fiber and viscoelastic material selections results in coating materials that enhance the reduction of vibration and noise
