Abstract
The present invention provides an improved method of manufacturing constrained layer dampers with a vulcanized rubber viscoelastic core. The method includes the steps of: applying a first layer of adhesive to a first constraining layer; applying a layer of unvulcanized rubber solved in a solvent to the first layer of adhesive to form a first laminate structure; applying a second layer of adhesive to a second constraining layer to form a second laminate structure; laminating the first laminate structure with the second laminate structure; coiling the laminated first and second laminate structures; and increasing the temperature of the coiled first and second laminate structures to thereby vulcanize the layer of rubber.
