摘要： A method for manufacturing a sandwich panel for a vehicle includes: etching a sheet, which etches one surface of a metal sheet; pressing the sheet, which forms a pattern of a specific shape on the one surface of the metal sheet; laminating a pair of the metal sheets; and performing injection-molding by injecting a plastic resin into the laminated pair of the metal sheets. The method may improve the bonding performance of the sandwich panel, thereby improving the degree of freedom of shape due to the press-molding.
