摘要： A fluid-filled may include including an outer barrier, a tensile member, and a fluid. The tensile member may be located within barrier and formed from a textile element that includes a pair of spaced layers joined by a plurality of connecting members. A method of manufacturing the chamber may include locating a textile tensile member between two polymer elements. Pressure and heat are applied to the tensile member and the polymer elements in a first area and in a second area. The pressure is greater in the first area than in the second area. In addition, the polymer elements are bonded together around a periphery of the tensile member.

摘要： A method of manufacturing a resin spring which can improve close contact between a spring body and inner-pressure generating members to reduce variations in load characteristics due to repeated deformation during use. The method of manufacturing a resin spring includes the steps of forming an elastomer preform having inner closed chambers, compressing the preform by applying an external force to produce a permanently deformed portion to form a spring body having at least one permanently deformed inner chamber, injecting an inner-pressure generating resin into each of the at least one permanently deformed inner chamber of the spring body, and molding the inner-pressure generating resin into an inner-pressure generating member by using the spring body as part of a die.

摘要： In a method for making a hybrid leaf spring, at least one layer of composite material is molded onto a primary leaf using a mold with an interior cavity having a curvature for receiving the primary leaf at a depressed camber relative to its initial camber. The depressed camber is between unloaded and curb load cambers of the hybrid leaf spring. The primary leaf and the layer of composite material are positioned in the mold adjacent to one another and with a layer of adhesive therebetween. The layer of adhesive is cured for bonding together the primary leaf and the layer of composite material at the depressed camber so as to generally eliminate bond line shear stress when the camber of the hybrid leaf spring is at the curb height.

摘要： 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.
