The invention discloses a preparation method for a composite material antenna cover with a thin-wall foam sandwich structure. The invention aims to solve the problem of difficult processing or incapable processing for a thin-wall foam sandwich layer in the process of preparation of an antenna cover with a sandwich structure. According to a technical scheme of the invention, processing of the entire body of the thin-wall foam sandwich layer comprises two steps: performing primary processing, namely subjecting an initial foam block to single-face mechanical processing; and performing secondary processing after subjecting the single-face mechanically processed foam block to reinforcing and rigidity increasing, i.e., subjecting the rest of faces of the thin-wall sandwich layer to processing on a combination of a rigid mold, a composite material panel and the single-face mechanically processed foam block so as to prepare the thin-wall foam sandwich layer meeting the technical requirements of a target antenna cover. In addition, through resin impregnation with fabrics and a vacuum bag molding technique, preparation of the composite material panel and bonding of the panel with the foam sandwich layer in the target antenna cover are realized. By adopting the preparation method provided by the invention, the difficulty of preparation of the thin-wall foam sandwich layer through processing of the entire body of the initial foam block is overcome; the molding process of the antenna cover is simple; and the prepared antenna cover has the advantages of few defects, light weight and good wave permeability.
