Unitized assembly including substructure element integral with fiber metal laminate

摘要

A unitized assembly may comprise a fiber metal laminate and at least one additive layer. The fiber metal laminate may have non-metallic plies bonded to metallic plies and may include an innermost metallic ply. The at least one additive layer may be deposited onto the innermost metallic ply by friction stir welding.

1. A unitized assembly, comprising:
a fiber metal laminate having non-metallic plies bonded to metallic plies including an innermost metallic ply; a first additive layer; and successively-applied additive layers; the first additive layer friction stir welded onto the innermost metallic ply, the first additive layer having a thickness less than each successively-applied additive layer, the innermost metallic ply having a thickness greater than a thickness of the other metallic plies; a boundary of a weld nugget joining the first additive layer and the innermost metallic ply is located above a first non-metallic ply and the weld nugget is smaller than a second friction stir weld nugget joining a successively applied additive layer to the first additive layer.
