Patent number: 10118321Abstract: A tooling apparatus for manufacturing a composite structure may include a rigid outer tool for receiving a composite layup, a tubular inner vacuum bag in contact with the composite layup and defining an inner vacuum chamber, and an outer vacuum bag covering at least a portion of the rigid outer tool. The outer vacuum bag and the tubular inner vacuum bag may collectively define an outer vacuum chamber containing the composite layup. An outer bag vacuum source may be fluidly coupled to the outer vacuum bag for applying an outer bag vacuum pressure on the outer vacuum chamber. An inner bag vacuum source may be fluidly coupled to the tubular inner vacuum bag for applying an inner bag vacuum pressure on the inner vacuum chamber during application of the outer bag vacuum pressure on the outer vacuum chamber.Type: GrantFiled: January 5, 2016Date of Patent: November 6, 2018Assignee: The Boeing CompanyInventors: Philipp Witte, Stanley W.

Patent number: 10071506Abstract: A vacuum bagging system may include a layer assembly defining a fluid flow channel. The layer assembly may include a contact layer mounted to a composite part positionable within an outer mold line (OML) tool. The contact layer may have a contact layer width defined by opposing contact layer side edges. The layer assembly may further include an inner layer mounted to the contact layer and having inner layer side edges located between the contact layer side edges. The fluid flow channel may extend along at least a portion of the composite part to at least one part end. The vacuum bagging system may include an internal vacuum bag positionable against the inner layer. An inner mold line (IML) tool may support the internal vacuum bag. The contact layer width may be less than an IML tool width.Type: GrantFiled: October 29, 2015Date of Patent: September 11, 2018Assignee: The Boeing CompanyInventors: Brett I. Lyons, Lisa C.

Patent number: 4789594Abstract: A laminated board is built up from a plurality of layers of composite material having substantially unidirectional fibers. The layers are arranged so that all of the fibers in the board are substantially parallel to the length of the board. The board is cut at alternate 60.degree. angles with respect to a bottom layer of the board in the direction of the fibers to form a plurality of strips having a substantially triangular cross section. The strips are then advanced through a rolling machine which forms radiused surfaces on two adjacent sides of an equilateral triangle which is described by the cross section of the strip. Tapered fillers are formed by varying the thickness of the board from one end to the other. A strip-cutting machine having an angled blade, guides for the board, and a mechanism for translating the blade with respect to the board is also disclosed.Type: GrantFiled: April 15, 1987Date of Patent: December 6, 1988Assignee: The Boeing CompanyInventor: Stanley W.
