US 2009/0020216 A1 · Method Of Making Tailored Core Laminated Sheet Metal

Abstract

A method for laminating metal sheets together with a first polymer selected for its adhesive characteristics and a second polymer selected for its viscoelastic characteristics. One of the first sheets of metal or second sheets of metal is fed across a first engraved roller having recesses that carry the first polymer and deposit the first polymer onto only selected regions of the sheet of metal. One of the first and second sheets of metal is across a second engraved roller having recesses that carry the second polymer and deposit the second polymer onto only selected regions of the sheet of metal. And then the first and second sheets of metal are married together so that the first polymer and the second polymer are engaged between the first and second sheets in different regions, and the polymers are cured to thereby attach the sheets together as a laminated metal sheet.
