PURPOSE:To provide steel sheet-clad aluminum sheets for automobiles, which enable the weight of materials to be reduced, and which are superior in vibration-damping properties, in relation to reducing the weight of an automobile body. CONSTITUTION:Skin materials are made of low carbon steel sheets 1, 2, and a core material is formed of an aluminum sheet, or of an aluminum alloy sheet 3. After each of the skin materials is laminated on each side of the core material by interposing non-crystallizable resin adhesives 4, 5 having vibration- damping properties between each skin material and the core material, the laminated sheet is pressed under heating. In this case, the resin layers are set to 0.02 to 0.3mm in thickness, whereby a sheet material whose weight is reduced, and which is superior in vibration-damping properties, can be obtained. |
