Abstract
A rigid metal-resin-metal sandwich laminate capable of withstanding 180.degree. bending with a threshold bending inner diameter of less than or equal to twice the total laminate thickness and suitable for use in the manufacture of building materials, containers, and particularly automotive parts including automotive outer panels is disclosed. The laminate comprises a resin layer sandwiched between and bonded to outer metal layers wherein the resin layer is comprised of a core sheet sandwiched between outer resin sheets, said core sheet being made of a resin which exhibits plastic behavior and which is bonded to said outer resin sheets with or without an adhesive layer, and said outer resin sheets being made of a ductile resin which does not exhibit yielding behavior or necking when stretched.
