Experimental Investigation of Sheet Metals Bond Strength Produced By Cold Roll Bonding Method (CRB)

In this research, the effect of sheet width on bond strength of aluminum specimensproduced through Cold Roll Bonding (CRB) was investigated. The samples were produced inwidths of 25 mm, 35 mm and 60 mm by CRB process with an amount of 50% thickness reductionat room temperature without using lubricant. Peeling test is a common method to evaluate the bondstrength of multilayer sheets, among several methods for doing this test such as floating roller test,T-Peel test, 90-degree test, 180-degree test, the T-Peel method has been selected. Test results showthe linear relation between bond strength and width, therefore as the sheet width increases, therequired force for peeling increases equally.
