SYSTEM AND METHOD FOR INTEGRALLY FORMING A STIFFENER WITH A FIBER METAL LAMINATE

摘要

A unitized assembly comprises a fiber metal laminate having at least one additive layer deposited thereonto such as by friction stir welding. The fiber metal laminate comprises metallic and non-metallic plies and having an innermost metallic ply. The innermost metallic ply and the additive layer are each sized and configured to facilitate the generation of thermal energy sufficient to deposit the first additive layer to the innermost metallic ply during the friction stir welding process. The additive layer is sized and configured to minimize thermal loads in the innermost metallic ply during deposition thereof. The unitized assembly may be formed using a stock member such as a metallic plate from which the innermost metallic ply may be machined. The metallic and non-metallic plies may be laid up over the innermost metallic ply. The substructure elements may be machined from the metallic plate.
