ABSTRACT:
A laminated sheet metal is comprised of a first sheet of metal and a second sheet of metal that are adhered together by a polymer layer core that is interposed between the two sheets and provides visco-elastic adhesion. The polymer layer has at least one region of a first polymer material that is selected for optimal viscous and elastic qualities by which to dampen the transmission of noise and vibration between the sheets, and at least one other region of a second polymer material that is selected for optimal adhesive qualities by which the sheets are optimally joined together against delamination. Thus the laminated sheet metal can be tailored to optimize the qualities that are desired for the manufacture of a particular product.
