Abstract:
One side of a metal sheet is joined to a polymer layer by applying heat to a joining area on the opposite side of the metal. The heat flows through the thin metal to activate a thermoplastic material or heat setting polymer into a bond with the metal. The method can be used to bond the metal sheet to a plastic body or another metal member. It is preferred to use a friction or friction stir tool to heat the metal surface.
