CONSTRAINED LAYER DAMPER

摘要

A method for installing a constrained layer damper on a product of manufacture is disclosed. The method includes applying a layer (16A) of first polymeric material to a substrate (10) of the product, wherein the first polymeric material is visco-elastic when solidified. Then, a second layer (16B) of polymeric material, which is stiff when solidified, is applied to the first polymeric material such that said first polymeric material is constrained between the second polymeric material and the substrate of the product. At least one of the layers of polymeric materials is dispensed in fluid form during the manufacture of the product from a bulk source of fluid material. The polymeric materials are chosen such that they do not require the application of heat above room temperature to solidify.
