ABSTRACT:
A process for forming a composite material from a core material having a first yield strength and a clad material having a second yield strength comprises passing the materials through at least one roll bite formed by at least two rolls rotating at different speeds relative to each other. A bond is formed between the core and clad materials by causing a reduction in the thickness of the materials as they pass through the at least one roll bite. The amount of reduction and the compressive force magnitude required to effect the bond is minimized. The process also includes applying back tension forces to the materials. In a preferred embodiment, different back tension forces are applied to the core and clad materials.
