A COMPOSITE STRUCTURE AND METHOD AND APPARATUS FOR MAKING SAME Abstract A composite structure comprises at least one ply comprising approximately parallel unidirected twines comprising helically-configured, matrix-impregnated, continuous strands of filament reinforcements to provide a flanged composite cantilever spring which serves as the principal constituent of a coupling structure. An interior ply of the structure comprises unidirected longitudinal twines configured at a body member extremity to provide a flange member connected to a cantilever spring. An exterior ply is disposed transversely of and superimposed upon the interior ply to provide the cantilever spring hinge line. The composite cantilever spring can be constructed to deflect about either a straight or curved hinge line. A method for making the structure comprises placing first ply loops of longitudinal twines upon a pin-ended forming surface, transversely placing a second ply of twines upon the first ply twines to deflect them into flange-forming cavities, hardening the twine-impregnating matrix, and removing and slotting the flanged spring members to provide the desired coupling structure.
