Abstract: A method and an automatic layup system for making a stack of a plurality of composite plies are presented. The automatic layup system includes a stacking assembly located in a first plane and a layup tool located in a second plane parallel to the first plane. The stacking assembly and the layup tool are movable towards each other. The method includes the steps of (a) providing one or more composite sheets between the layup tool and the stacking assembly, (b) generating a first composite ply from the one or more composite sheets, (c) placing the first composite ply on the layup tool by the stacking assembly by bringing the stacking assembly and the layup tool close to each other, and (d) repeating the steps (b) and (c) for generating and placing a second composite ply on the first composite ply, which is placed on the layup tool.

Abstract: A gas turbine engine composite article having a composite article airfoil extending outwardly to an article root to an article airfoil tip. Within the article airfoil is a core including a core airfoil attached to a core root including a core dovetail. A continuous outer three-dimensional braided layer including braided composite material tows are braided on the core and the braided layer covers the entire core airfoil and the core root. The core may be an inflatable mandrel or a composite core made of a composite material. The core may include stiffeners such as an I beam or hollow rectangular cross-section box beams. A method for making such an article includes braiding a continuous outer three-dimensional braided layer including braided composite material tows on the core including covering the entire core airfoil and the core root with the continuous outer three-dimensional braided layer.

Abstract: A system for forming stacked material includes a housing defining an interior space. The housing includes a bottom wall and a side wall coupled to the bottom wall. At least one tool is configured to shape the stacked material. The at least one tool is disposed within the interior space. A membrane extends at least partially over the bottom wall and is spaced a distance from the bottom wall. The membrane is configured to move towards the bottom wall. At least one intensifier mechanism is disposed in the interior space and is configured to induce a force against a portion of the stacked material and against the at least one tool as the membrane is moved towards the bottom wall.

Abstract: Various adaptive apparatus and systems for automated handling of components such as composite plies are provided. In one embodiment, a ply manipulation system is provided that comprises an automated machine having an arm, and a ply manipulation tool attached to the arm of the automated machine. The ply manipulation tool includes a first shuttle including a first gripper, a second shuttle including a second gripper, and an actuator. The ply manipulation system further comprises a processor that automatically controls the actuator to move the first and second shuttles linearly with respect to one another to adapt the first and second grippers to a ply shape. In another embodiment, the first and second shuttles include one or more clamping elements moveable to a position to be deployed outside a perimeter of the ply. Methods for removing a ply from a sheet of material using a ply manipulation tool also are provided.
