Abstract: 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.
