ABSTRACT:
A noise-damping composite is formed by providing a sandwich of a viscoelastic layer between two metal skins, the viscoelastic layer including electrically conductive particles distributed therein. The sandwich is passed through a series of cells of an electro-galvanizing line, in each cell the sandwich passing through the nip formed between a charged electrically conductive contact roller and an electrically insulating pressure roller for applying sufficient pressure to insure conductivity from the metal skin engaging the contact roller through the viscoelastic layer to the other metal skin, so that the galvanizing metal is plated on only the outer surfaces of the two metal skins.
