    摘要： 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 that comprises multiple pick-and-place (PNP) machines, 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 PNP machines, applying a vacuum to hold the preform in contact with the strong back, transporting the preform to a mandrel via the PNP machines, and placing the preform onto the mandrel.

    摘要： Wing panels having composite wing skins and stringers are produced on a moving production line (88). The wing panels are formed on tools (90) that move through workstations (92-114) along the production line where laminators (124a-124d) layup the wing skins and pick-and-place machines place stringers on the wing skins that are supplied by stringer feeder lines.

    摘要： A roller (110) for automated fiber placement includes a flexible rim member arranged about a central axis. The flexible rim member (180) has an inner side and an outer side, and the central axis is closer to the inner side than to the outer side. The roller also includes a hub member (122) arranged substantially concentric with the flexible rim member about the central axis (302). The hub member (122) defines an opening (140) to receive a shaft of an automated fiber placement machine. The roller further includes a plurality of curved interconnect members (124) extending between the hub member (122) and the flexible rim member (180). Each of the plurality of curved interconnect members (124) is elastically deformable to accommodate deformation of the flexible rim member. The roller also includes one or more roller skin layers (182, 184, 186, 188) coupled to the outer side of the flexible rim member.
