Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a sandwich panel for a vehicle, the method comprising: etching a pair of metal sheets, which etches one surface of each metal sheet of the pair of metal sheets; pressing the pair of metal sheets, which forms a pattern of a same specific shape on the one surface of each metal sheet; laminating the pair of metal sheets so that the one surface of each metal sheet of the pair of metal sheets, on which the pattern is formed, faces the other; and performing injection-molding by injecting a plastic resin into a void portion formed inside the laminated pair of the metal sheets through an injector formed in the sandwich panel, wherein the void portion is formed by the pattern on each metal sheet of the pair of metal sheets. 2. The method of claim 1 , wherein etching the pair of metal sheets etches each metal sheet by immersing each metal sheet into an etching solution. 3. The method of claim 2 , wherein an undercut is formed on the one surface of each metal sheet of the pair of metal sheets by etching the pair of metal sheets.
