Abstract
A composite sheet including a first polymer layer laminated to the first major surface of a ferromagnetic substrate having opposing first and second major surfaces. A second polymer layer is laminated to the second major surface of the substrate, sandwiching the substrate between the first and second polymer layers. The substrate is preferably steel having a thickness preferably between about 1 to 3 mils. A significant advantage of the composite sheet is the increase in the utility of the composite sheet due to the composite structure.
