Aluminum sandwich panels are prepared by various methods, including adhesive connection method, laser welding connection method, sewing connection method and so on. Among them, the adhesive connection method is a simple and convenient method, but there are lower strength and easy delamination under high temperature and corrosive conditions to destroy the shortcomings; laser welding connection method is a complex process, the production time is longer; stitching connection method is a complex production process and the strength of the connection is low.
