    Abstract: Methods and tools for forming composite structures with predetermined, non-planar patterns of contours, as well as apparatuses including such composite structures, are disclosed herein. Example methods include defining a pattern of contours in a flexible sheet of composite material, conforming the flexible sheet of composite material to a layup mandrel, and curing the flexible sheet of composite material. Example tools include a body with an engagement surface for engaging a flexible sheet of composite material, the body having regions of relative stiffness and regions of relative compliance, and a vacuum distribution manifold configured to selectively apply a vacuum to the regions of relative compliance to deform the engagement surface to define a predetermined, non-planar pattern of contours.

    Abstract: Systems and methods for defining a surface contour of a layered charge of material are disclosed herein. The systems include a forming die, which includes a forming surface shaped to define a desired surface contour of the layered charge, and a fluidly actuated support, which includes a support surface that is adjacent to the forming surface and located to support the layered charge. The systems further include a vacuum bag that at least partially defines an enclosed volume and a vacuum source configured to selectively apply a vacuum to the enclosed volume. The methods include locating the layered charge on the forming surface and on the support surface, covering the layered charge with the vacuum bag to define the enclosed volume, applying the vacuum to the enclosed volume, compressing the fluidly actuated support, translating the support surface, and deforming the layered charge to define the desired surface contour.

    Abstract: A composite part, such as a stiffener is formed in place. A composite charge is placed on a tool spanning a mold cavity, with the centerline of the charge offset from the centerline of the mold cavity. Opposite sides of the charge are held against the tool as the charge is formed into the mold cavity. One side of the charge is held against movement on the tool while the other side of the charge is allowed to slip over the tool toward the mold cavity.

    Abstract: Systems and methods for assembling a skin of a composite structure are disclosed herein. The methods include operatively attaching a charge of composite material to a flexible substrate to define an initial conformation for a composite-substrate assembly and locating the composite-substrate assembly and a layup mandrel proximal to one another. The methods further include pressing the composite-substrate assembly against an outer surface of the layup mandrel to deform the composite-substrate assembly to a final conformation. The methods also include affixing the charge of composite material to the outer surface of the layup mandrel and releasing the charge of composite material from the flexible substrate while retaining the charge of composite material on the outer surface of the layup mandrel. The systems include the flexible substrate, the layup mandrel, and an assembly deformation structure that is configured to press the composite-substrate assembly against the outer surface of the layup mandrel.
