COMPOSITE PANELS, COMPOSITE PANELS SANDING EQUIPMENT, AND COMPOSITE PANELS MANUFACTURING METHODS

Abstract

This invention proposes a composite plate, a composite plate roughening device, and a composite plate fabrication method, and addresses the field of sheet metal materials engineering. The composite plate consists of a first plate and a second plate, in which the first side of the first plate is textured, the first side of the second plate and the first side of the first plate are rolled for bonding, and the adjacent textures with a spacing of 0.005 mm to 0.03 mm account for more than 90% of all textures. For the composite plate described in the designs of the invention, the first side of the first plate is roughened so that the first side of the first plate and / or the first side of the second plate is textured, increasing the bearing area of ​​the first and second plates, thereby giving the composite plate formed by combining the first and second plates higher bonding strength and thus a more stable bond.
