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: An apparatus for forming composite members has a frame assembly which is lowered onto a table. A sheet of vacuum bagging material, supported by the frame, covers a tooling surface on the table. Attached to the sheet is a downwardly depending seal which continuously extends around the sheet's periphery. This seal inserts into an upwardly opening channel that surrounds the perimeter of the table's tooling surface as the frame is lowered. The seal is inflated while in the channel and this provides in airtight seal between the sheet and tooling surface.
