| 61 | Method of manufacturing hybrid composite leaf springs | US184548 | 1994-01-21 | US5425829A | 1995-06-20 | Jemei Chang |
| A hybrid composite automotive leaf spring comprises parallel glass and polyethylene terephthalate fibers distributed in a pattern replicated throughout a resin matrix. A method of producing the hybrid composite leaf spring comprises winding various proportions of glass and polyethylene terephthalate or nylon fibers together into a homogeneous mass in an epoxy matrix in a mold to form a blank, which is then compressed and cured into a leaf spring having a predetermined homogeneous mixture of parallel fibers distributed throughout the cross-section of the spring. The unitary spring has a spring rate that is a composite of the resin-bonded glass and other fibers. Different spring rates are obtained by varying the percentage content of the glass and other fibers, while maintaining the homogeneity of the resultant leaf spring. | ||||||

| 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 a coupling structure body member 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 preferred tubular form of the coupling structure comprises at least one end configured as a polygonal array of flanged cantilever springs which serve as the socket end of a spring-lock coupling used to connect mating flanged spigot-end structures. A preferred segmented form of coupling structure comprises two semi-circular flanged cantilever spring members assembled and deflected by an encircling retaining sleeve.The method and apparatus for making a composite in the form of a preferred coupling 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, removing and slotting the flanged spring members to provide the desired coupling structure. | ||||||

| A method of producing useful hollow bodies and the resulting products. The hollow bodies are formed by providing a block of thermoplastic elastomer material having a selected initial axial height and providing the block with a selected axial core opening. An axial force is applied to said block sufficient to compress said block a substantial extent to reduce the free height of the block and expand the core opening transversely outwardly to define sidewalls for the hollow body. The axial force is removed, and the hollow body is prepared for use as a compression spring or other useful device. | ||||||

| A preform is made by casting a copolyester polymer elastomer into a block. While the block is solidifying, pressure is supplied to the central portion thereof. After a block is formed, it is annealed and a precompression force is applied thereto sufficient to compress the block to an extent greater than thirty percent of the original dimension of the block as measured parallel to the precompression force. In one embodiment a cushioning unit using the block is made by placing a pair of multi-apertured metal plates on opposite sides of the block with projections on the plates extending against the block and applying a second precompression force to the block and plates sufficient to cause the copolyester polymer elastomer to flow into the apertures in the plates and form a mechanical bond between the block and the plates. | ||||||
