Abstract: Methods and apparatus for semi-automated tack welding of plies of a thermoplastic composite layup are described. An example welding tool includes a stabilization foot, a housing, a compaction foot, and a welder. The stabilization foot has a stabilization surface. The housing has a central axis. The housing is movable relative to the stabilization surface along the central axis of the housing. The compaction foot has a central axis and a compaction surface. The compaction surface is movable relative to the stabilization surface and to the housing along the central axis of the compaction surface. The welder has a central axis and a welding surface. The welding surface is movable relative to the stabilization surface, to the housing, and to the compaction surface along the central axis of the welder.

Abstract: Riblets may be formed in aerodynamic surfaces to reduce drag by forming a composite material layup, molding the riblets into a surface of the layup, and curing the layup.

Abstract: A retail system for implementing planograms includes a communications network, a central computing system, and a plurality of retail computing systems. The central computing system is configured to receive and to transmit a plurality of planograms, each planogram being associated with one retail store of a plurality of retail stores and a plurality of products to be displayed for sale at the associated retail store. Each planogram includes data indicating threshold quantities of each product of the associated plurality of products. Each retail computing system is at a corresponding one of the plurality of retail stores and is configured to receive, via the communications network, planograms associated with the corresponding retail store and to receive inventory information indicating in-stock quantities of the plurality of products associated with each planogram.

Abstract: An apparatus and accompanying method for handling fabrics used in the construction of composite components and in particular those used in aircraft includes a movable, gantry-type frame assembly having a movable robotic arm attached thereto. A drum assembly, attached to the robotic arm has one or more vacuum ports disposed along the surface of the drum. When vacuum from within the drum is applied to the ports and the drum is moved to contact flexible fabric material—such as the reinforcement fabric used for composite manufacture—an end of the fabric may be picked up through the effect of the applied vacuum and the fabric rolled-up around the drum. The movable gantry and/or the robotic arm may then move the drum to a desired location where the fabric is unrolled and prepared for composite manufacture. Variations to the vacuum ports permit the rolling and transport of a variety of materials and shapes.

Abstract: A method of forming a unitary, composite structural member, and a member formed in accordance with the process. The process involves stitching a plurality of warp knit panel sections together to generally form a plurality of independent panel sections. The sections are placed within the dies of a molding tool such that a rib portion of each section aligns. Inflatable bladders are then slipped into voids formed in between the various panel sections of the assembly. The bladders are inflated to hold the panel sections in the shape of the final product and to hold the rib portions in contact with one another. Resin is then infused into the panels that make up the assembly. The assembly is then cured. When the panels are removed from the molding tool a unitary, complexly shaped, composite structural member is formed.

Abstract: A three dimensional textile joint reinforcement joins and reinforces a composite panel and a support structure. The composite panel includes lamina of textile fibers in the plane of the panel. The joint reinforcement is attached to the composite panel by staples. The support structure, which is typically perpendicular to the plane of the composite panel, is also attached to the joint reinforcement. Out of plane forces act upon the assembled structure and the joint reinforcement transfers out of plane loads between the support structure and the composite panel. The staples provide transfer of load to the plane of the textile fibers in the composite panel, where the composite panel is strongest.

Abstract: A mold apparatus and method for resin film infusion molding including an outer mold tool having a facing sheet adapted to support a resin film and preform assembly. The facing sheet includes attachment features extending therefrom. An inner mold tool is positioned on the facing sheet to enclose the resin film and preform assembly for resin film infusion molding. The inner mold tool includes a plurality of mandrels positioned for engagement with the resin film and preform assembly. Each mandrel includes a slot formed therein. A plurality of locating bars cooperate with the slots and with the attachment features for locating the mandrels longitudinally on the outer mold tool.
