Abstract
A metal-plastic-metal structural laminate which can be formed into various useful articles having compound curves using conventional metal forming techniques. The laminate comprises two metal skin layers and a centrally disposed polymer layer comprising a core layer, and optionally first and second adhesive layers. Each metal skin layer is 2 to 20 mils, the ratio of the core thickness to skin thickness is less than 9:1 and the total laminate thickness is 5 to 65 mils. The laminate can be bent to 90.degree. to a critical radius, the distance between the pivot point and the inner skin surface of the laminate, without metal rupture.
