  • Publication number: 20240262045
    Abstract: A tacking element for tacking workpieces in composite manufacturing includes a base member, an actuating member and a heating member. The actuating member secured to the base member. The heating member disposed on the base member or the actuating member and configured to selectively radiate heat toward the actuating member. The actuating member is configured to transform from an inactive position to an active position in response to the heat from the heating member. A tacking stick and system that implements the tacking element is provided. A method for tacking workpieces in composite manufacturing is also provided.

  • Publication number: 20240253316
    Abstract: A method for preforming a workpiece includes engaging a conformable member with a work surface of a worktable upon which the workpiece is prepositioned. The worktable is used to shape the workpiece to a desired shape. The conformable member retains the workpiece and disengages from the worktable while maintaining the desired shape of the workpiece. A system for preforming the workpiece includes the conformable member and the worktable. A composite manufacturing method and additional methods for preforming the workpiece are also provided.

  • Publication number: 20240083043
    Abstract: The electroadhesive pad comprises a substrate, a first electrical network, and a second electrical network. The first electrical network comprises a first subset of electrodes and a first voltage source configured to apply an output voltage at a first polarity to the first subset of electrodes. The second electrical network comprises a second subset of electrodes and a second voltage source configured to apply the output voltage to the second subset of electrodes at a second polarity. The first and second voltage sources are disposed along a central region of the electroadhesive pad. The first and second subsets of electrodes are supported by the substrate and extend between the central region and a perimeter of the electroadhesive pad. The methods include producing a custom electrostatic pad by mapping a shape of the custom electroadhesive pad onto a stock electroadhesive pad and cutting the stock electroadhesive pad into the shape.

  • Publication number: 20230330950
    Abstract: An apparatus includes a support platform and a plurality of passive actuators coupled to the support platform. Each one of the plurality of passive actuators includes a shaft. The shaft includes a first shaft end and a second shaft end, opposite the first shaft end. Each one of the plurality of passive actuators includes a gripper coupled to the second shaft end. The shaft is freely movable relative to the support platform in a first direction along an axis of linear shaft movement. Movement of the shaft relative to the support platform in a second direction, opposite the first direction, along the axis of linear shaft movement is automatically inhibited.
