  • Publication number: 20220347941
    Abstract: A manufacturing system includes a cutting machine, an adhesion machine, and a pick-and-place system. The cutting machine sequentially cuts a continuous length of a unidirectional prepreg into prepreg segments. Each prepreg segment has an opposing pair of segment cut edges that are non-parallel to a lengthwise direction of the unidirectional prepreg. The adhesion machine has a conveyor belt and an adhesion station. The pick-and-place system sequentially picks up the prepreg segments from the cutting machine, and places the prepreg segments in end-to-end relation on the conveyor belt, and in an orientation such that the segment cut edges are generally parallel to a lengthwise direction of the conveyor belt. The conveyor belt feeds the prepreg segments to the adhesion station. The adhesion station adheres the prepreg segments to a continuous length of a backing material, thereby resulting in a continuous length of a backed cross-ply prepreg.

  • Publication number: 20220314556
    Abstract: A system for forming a composite stiffener includes a support surface to support a composite sheet and a sheet-locating device to locate the composite sheet such that a first sheet-portion is supported on the support surface and a second sheet-portion extends beyond the support surface. The system includes a separation device to separate the second sheet-portion from the first sheet-portion to at least partially form a composite charge. The system includes a layup tool including a longitudinal tool-axis and a layup surface configured to receive the composite charge. The layup surface includes a curvature along the longitudinal tool-axis. The system includes a compaction device to compact the composite charge on the layup surface. The system includes a tool-positioning device to position of the layup tool such that a compaction force, applied to the composite charge by the compaction device, is normal to the layup surface.

  • Publication number: 20220281102
    Abstract: There is provided a mechanical avatar assembly for use in a confined space in a structure. The mechanical avatar assembly includes a rail assembly for attachment to an access opening to the confined space. The rail assembly includes two or more rail segments coupled together to form an elongated base having a rail and a gear rack extending along a length of the elongated base. The rail assembly further includes a carriage portion coupled to the rail, and movable relative to the rail, and a drive assembly coupled to the carriage portion and to the gear rack, to move the carriage portion along the rail. The mechanical avatar assembly further includes an articulating avatar arm coupled to, and movable via, the carriage portion. The mechanical avatar assembly further includes an image capturing device.

  • Patent number: 9517615
    Abstract: A backing film removal system including a substrate support member configured to support a substrate, where a backing film is attached to the substrate, a backing film separating member arranged operatively with respect to the substrate support member such that at least a portion of the backing film separating member is positionable between at least one portion of the substrate and backing film when the substrate is disposed on the substrate support member, a backing film holding member configured to maintain a separation between the substrate and backing film at the at least one portion of the substrate and backing film, and at least one drive unit connected to one or more of the substrate support member and the backing film separating member and operable to cause relative movement between the substrate support member and the backing film separating member.

  • Patent number: 9358770
    Abstract: A method for initial separation of an adhered backing film from an uncured pre-impregnated composite lamina having an edge includes exposing and supporting the edge of the composite lamina, and applying an impact force to the exposed edge with an automated tool. The impact force is sufficient to cause delamination of the backing film from the composite lamina without damaging the lamina.
