Abstract: An example method of forming a composite structure is described that includes applying a laminated charge onto an expandable pallet, moving the expandable pallet at a translation rate and relative to a die conveyor that comprises a plurality of die sections, and driving the plurality of die sections on the die conveyor at an angle relative to the expandable pallet so as to drive the plurality of die sections progressively deeper into a recess defined by the expandable pallet and shape the laminated charge into at least part of a shape of the composite structure.

Abstract: Tape layup systems and associated methods. A tape layup system includes a feed spool and an uptake spool. The feed spool is configured to carry a tape roll of tackifier tape that includes a tackifier material and a backing material, and the uptake spool is configured to carry a backing material roll of the backing material. The tape layup system further includes a torque transmission system configured to convey a torque from the feed spool to the uptake spool. The tape layup system is configured such that conveying a torque from the feed spool to the uptake spool operates to draw the backing material onto the backing material roll. A method of operating a tape layup system includes generating tension in a tackifier tape to rotate a feed spool and consequently rotating an uptake spool to draw a backing material onto a backing material roll.

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 performing vacuum securement of an object. The method includes covering the object with an impermeable membrane, locating a vacuum port at the impermeable membrane, and applying a negative pressure to the vacuum port that offsets air leaks between the impermeable membrane and the object.

Abstract: Systems and methods are provided for bi-directional cutters for Automated Fiber Placement (AFP) machines. One embodiment includes a bi-directional cutter for Automated Fiber Placement (AFP) manufacturing. The cutter includes a cutter body that has an upper edge and a lower edge, and has an opening placed between the upper edge and the lower edge that is dimensioned to enable passage of a tow of fiber through the cutter body. The cutter also includes a first blade disposed on the lower edge of the cutter body that is oriented to cut the tow when the cutter is driven downward, and a second blade disposed on an edge of the opening in the cutter body that is oriented to cut the tow when the cutter is driven upward.

Abstract: A method, system and computer-readable storage medium are provided to facilitate inspection of a composite part during manufacture. In the context of a system, a system for inspecting a composite part during manufacture is provided that includes an inspection system configured to detect an in-process anomaly with respect to a ply of the composite part during placement of the ply. The system also includes a computing system configured to determine part location coordinates of the in-process anomaly detected by the inspection system with respect to the ply of the composite part. The computing system is also configured to map the in-process anomaly to a digital part model based upon the part location coordinates. The system additionally includes a display, responsive to the computing system, configured to present a representation of the digital part model including an indication of the in-process anomaly relative thereto.
