Bonded lightweight structural sheet

摘要

Laminated composites such as noise damping sheet metal sandwiches with viscoelastic adhesive cores are strengthened against delamination during forming and made more conductive for welding. Electrically conductive, metal-element containing particles, wires, wire meshes, or the like conductive bonding elements are included in the core material and fused to facing surfaces of the metal sheets to provide many mechanical bonding connections and electrical connections over the bonded area of the composites.
