ABSTRACT:
A method for fabricating multi-sheet structures in which a first sheet is arranged on a planar support and a blowing agent is placed on at least one selected portion of the first sheet. A second sheet is positioned over the first sheet so that the second sheet overlies the selected portion of the first sheet and the first and second sheets are then secured together by friction stir welding in a pattern which encloses the selected portion of the first sheet. Additional sheets may be secured together in a like fashion. Thereafter, the sheets are heated to a temperature sufficient to decompose the blowing agent.
