Abstract: Amethod for constructing a composite structure is disclosed. The method comprises four steps. Step one calls for coupling a flexible layer to a base, where the flexible layer has a working surface and an underside surface. Step two requires coupling at least one support element to the underside surface of the flexible layer. The next step calls for coupling at least one adjustable element to the support element for adjusting the position of the flexible layer. The last step requires configuring the flexible layer to a configuration suitable for constructing the composite structure. More specifically, the flexible layer may have internal reinforcing elements for added strength and durability.

Abstract: A method of forming fabric for making foam-in-place molded articles such as preferably seat cushions. A film is secured to a frame and tacked by adhesive to a piece of fabric, not secured to the frame, that forms the outer covering of the seat cushion for permitting the fabric to move relative to the film during forming to enable fabrics which cannot stretch a considerable amount to be used. To form the fabric, the film and fabric are placed in a female mold and the film and fabric are drawn into a cavity of the mold and against a contoured surface in the cavity forming a recess in the film and fabric. To counteract compressive stresses in the fabric during forming, the frame can have one or more fabric tensioners that selectively apply tension to the fabric during forming. To mold the cushion, a foam is poured into the recess and allowed to cure until it hardens into a foam core and bonds with the film.

Abstract: A hybrid metal/composite spinner cone used in aircraft applications and a method of manufacturing the same. The spinner cone has a metal outer shell which is bonded during the molding process to an inner structural member of thermoplastic composite.

Abstract: A method for forming stabilized preforms for complex composite articles is disclosed using a solid meltable uncatalyzed thermosetting resin as the stabilizing agent. The resin is applied to each layer of the preform and heated to melt the resin and bond the layers together. After cooling, the resin resolidifies but does not set and thereby holds the layers in the desired preform shape. The layers can be first formed into a flat sheet as a raw material from which shaped preforms can be made by cutting the sheet into sections which are placed over a mandrel and reheating to thereby remelt the solid resin to allow the preform to conform to the shape of the mandrel. Utilizing this process allows complex composite parts to be easily preformed and assembled prior to placement in a mold for resin injection molding, without inhibiting part strength as the resin is compatible with the injection resin and is cocatalyzed by the catalyst contained in the injection resin.
