    Abstract: A method and apparatus for holding a part on a fixture in a precisely known predetermined position includes pressing a surface of the part against a vacuum head and sealing an annular elastomeric sealing ring against the part surface. A valve button of a valve is engaged by the part surface to open the valve and establish communication between a vacuum source. The part is pulled by the vacuum against a hard stop in the vacuum head having a fixed precisely known relationship to said vacuum head reference surface. The hard-stop can be mounted in the base of the vacuum head for pivoting about at least one axis to self-align the hard-stop face with the part face.

    Abstract: A reconfigurable fixture for holding a plurality of workpieces in proper position for manufacturing. The fixture includes an array of interleaved uniformly spaced contoured headers, with a predetermined set of headers corresponding to a predetermined workpiece contour. Each set of contoured headers may be simultaneously laterally displaced from an inactive stored position to a locked, active forward position, wherein the selection and movement of the set of headers is controlled by a computer controller. Each contoured header has a set of vacuum cups, that, when activated, pulls the predetermined workpiece against the contoured edges of the predetermined set of headers.

    Abstract: A forming tool and method for its use with flat pre-preg composite laminate assemblies which incorporates a mandrel segmented into multiple forming blocks, the forming blocks sized to receive a draped composite laminate assembly with all portions of the composite laminate assembly spaced from a shaping surface on each block. A spline plate engages the shaping surface of the forming blocks to provide a neutral axis for maintaining the entire composite laminate assembly in tension during forming. In the exemplary embodiments, the draped composite laminate assembly is formed to the forming blocks from the flat composite laminate assembly and maintained in contact with the forming blocks using a vacuum bag. The mandrel forming blocks arc then displaced to a desired curvature on the spline plate.

    Abstract: Apparatus and methods provide for utilizing continuous curved composite stringers to control the loads and corresponding moments within curved regions of an aircraft or other vehicle without delamination or other interlamina failures. According to embodiments described herein, any number of tapered height curved composite stringers may be coupled to continuous skin components to create a curved continuous panel. The tapered height curved composite stringers may have webs that taper to a reduced height within curved regions and corresponding base flanges that widen during web tapering. Reinforcement fittings may be coupled to the base flanges in the curved regions for further strengthening and to provide for the attachment of supplemental panels to the stringers.
