Abstract: Described herein are flexible truss systems and methods of transferring flexible composite parts using these systems. A flexible truss system comprises a flexible truss mechanism and composite pick-and-place mechanisms supported on the flexible truss mechanism and designed to attach to various composite parts. The flexible truss mechanism comprises flexible elongated members and slidable ribs coupled to each flexible elongated member. Specifically, each rib is slidably coupled to at least one flexible elongated member. In some examples, each rib is also fixedly coupled to another flexible elongated member. The slidable coupling allows the flexible truss mechanism to bend and follow the shape of a supported part, such that the composite pick-and-place mechanisms are able to contact and support different areas of the composite part. As such, the same flexible truss mechanism is able to support flexible composite parts having different shapes.

Abstract: Systems and methods are provided for placing preforms onto a mandrel. One illustrative method includes moving a mandrel in a process direction relative to a station(s) that comprises multiple pick-and-place machine(s), identifying a tray that stores a preform comprising an unhardened fiber-reinforced material, placing the strong back at the preform via at least one of the pick-and-place machine(s), applying a vacuum to hold the preform in contact with the strong back, transporting the preform to a mandrel via the pick-and-place machine(s), and placing the preform onto the mandrel.

Abstract: Systems and methods are provided for compacting laminates. One embodiment is a method for compacting a laminate onto a surface of a forming tool. The method includes placing the laminate onto the forming tool, disposing a compaction device over the laminate, gripping the compaction device to the forming tool, compacting the laminate with a pressure foot of the compaction device, and removing the compaction device from the forming tool.

Abstract: Embodiments include apparatus for compacting an object onto a rigid tool by applying a negative pressure while the scroll of material overlays the object. The apparatus comprises one or more spindles and a scroll of material that is stored on the one or more spindles. The scroll of material comprises a permeable layer and an impermeable membrane wherein the impermeable membrane contacts the permeable layer and may extend beyond a perimeter of the permeable layer.

Abstract: Described herein are methods and systems for manufacturing composite stringers using independently movable pallets with independent vacuum controls. Specifically, a stringer forming system comprises a base plate and a plurality of sets of pallets (e.g., two or more sets of pallets), slidably coupled to the base plate and forming an adjustable cavity. Each pallet comprises a primary vacuum zone, fluidly connected to a separate vacuum port. The system allows for independent application of a reduced pressure to the primary vacuum zone of each pallet. For example, a reduced pressure is applied only to pallets that are already covered with a composite layup and to pallets that are being covered. Any pallets that are exposed are kept at an ambient pressure and decoupled from a vacuum source, thereby reducing the vacuum leakage through the overall system. As the composite layup is being formed over new pallets, these new pallets are subjected to the reduced pressure.

Abstract: Systems and methods are provided for vacuum handling of composite parts. One embodiment is a method for picking up, placing, and compacting an object. The method includes covering a part of an object with an impermeable membrane, applying a negative pressure via an end effector that is sufficient to offset any air leaks between a first portion of the impermeable membrane and the object, thereby forming a suction hold that secures the object to the impermeable membrane, and transporting the object to a rigid tool while the suction hold is retained. The method further comprises applying a negative pressure via the end effector that offsets air leaks between a second portion of the impermeable membrane and the rigid tool, thereby forming a suction hold that compacts the object to the rigid tool.

Abstract: Systems and methods are provided for handling objects. One embodiment is an apparatus for handling objects. The apparatus includes a vacuum securement head. The vacuum securement head includes a strongback, and an array of end effectors arranged at the strongback in conformance with a contour. The contour is complementary to a pickup tool. The array of end effectors is configured to pickup objects at the pickup tool. The vacuum securement head also includes an impermeable membrane that is penetrated by the end effectors, and a vacuum system configured to provide suction through the end effectors. The suction is configured to remove air between the impermeable membrane and a rigid tool, and offset air leaks between the impermeable membrane and the rigid tool.

Abstract: Systems and methods are provided for compacting objects onto tools. One embodiment is a method for compacting an object onto a rigid tool. The method includes placing an object onto a surface of a rigid tool, disposing an end effector over the object, spreading linkages of the end effector, causing a scroll of material between the linkages to be disposed atop the object while surrounding the object, and applying a negative pressure to the scroll that offsets air leaks between the scroll and the object, thereby forming a suction hold that compacts the object onto the rigid tool.
