Abstract:
1. A laminated sheet metal comprising: a first sheet of metal and a second sheet of metal; a single polymer core layer interposed between the first and second sheets to provide visco-elastic adhesion between the sheets, said single polymer core layer being of at least one region of a first polymer material selected for optimal adhesive qualities by which the sheets are joined together against delamination, and at least one region of a second polymer material selected for optimal viscous and elastic qualities by which to dampen the transmission of noise and vibration between the two sheets, said at least one region of the first polymer material and said at least one region of the second polymer material lying side-by-side and being contiguous with one another to cooperate in providing the single polymer core layer interposed between the first and second sheets.
