Abstract: A flexible punch and die are used to form a flat composite laminate charge into a stiffener having a desired cross sectional shape. A desired contour is formed in the stiffener by bending the punch and die. Ply wrinkling is avoided during contouring by maintaining those portions of the stiffener subject to wrinkling in tension as the contouring is being performed. Bridging of the plies during the contouring process is avoided by first contouring those sections of the stiffener that are subject to wrinkling, and then contouring the remaining sections of the stiffener.

Abstract: An apparatus for supporting a wing assembly at a wing assembly support height. Base sections are provided, each having a different predetermined height with respect to one another. A movable platform carries a plurality of base sections, and a plurality of wing assembly support sections rest on base sections and include wing assembly connectors, which are movable in a first plane and a second plane generally perpendicular relative to the first plane. A differential height is defined between the wing assembly support height and the combined heights of the platform and the height of wing assembly connector, relative to the bottom of the wing assembly support section. At least one of the base sections is of a predetermined height approximating the differential height and is carried on the platform. The wing assembly support section is carried on such base section.
