Influence of Thickness on Tensile Property of Copper Foil
This study deals with the influence of thickness of copper foil on its tensile property. Tensile tests were carried out on copper foils with various thickness ranging from 5 μm to 2 mm in air. Then, the tests on copper foil with the thickness of 20 μm and copper sheet with the thickness of 2 mm were also conducted in a scanning electron microscope, and their deformation was examined during testing using an electron backscattered diffraction method. The influences of thickness of copper foil on its deformation, tensile strength, and fracture morphology were investigated. As a result, the tensile properties of copper foil depend on its thickness, and the tensile strength decreased when the foil thickness was thinner than the grain diameter.
