Abstract:

   There is a growing need for lightweight materials and lightweight construction for energy saving. For this reason, interest in double-layer sheets has increased in the last decade. The fact that the double layer materials are lightweight compared to the monolithic materials of the same thickness and that they can have different properties together is the reason for this increase. Double layer sheet metal is obtained by combining two metallic sheets with various methods such as cold rolling, pressure welding, hot rolling or adhesive bonding. These sheets are used to provide properties that can not be achieved with a monolithic sheet. The desired electrical and thermal characteristics, lightness, corrosion resistance and shock absorbing structure can be achieved with the developed double layer sheet metals. In this study, a double layered structure was obtained by using a polychloroprene based adhesive and combining sheet metals of different thicknesses and different materials under different forces. The obtained double-layered sheets were subjected to peeling test to determine adhesion properties and parameters (force, sheet metal type) affecting these properties. All the experiments were made according to the full factorial experimental design and the results were examined. As a result of the study, it is seen that the sheet metal type is the most important factor in the adhesion of the double layer sheets.
