    Abstract: A method for bending towpreg to yield a desired amount of axial force during bending to form a preform is provided including inserting towpreg into a bending die, applying an initial axial force to the towpreg, and moving the gripped end of the towpreg in an involute path using a cam, a cam follower and a gripper, the gripper disposed on the cam follower. Axial force between the gripped end and the stationary end of the towpreg from a point where the towpreg contacts a surface of the bending die is applied tangent to the surface of the bending die while bending the towpreg. An apparatus for bending towpreg to form a preform is provided including bending dies disposed in fixed positions, and a follower. Axial involute cam mechanism having a drive shaft, a cam, a cam follower that follows an involute path around the cam, a gripper and a clamp.

    IPC: B29B17/00

    Abstract: A method of reprocessing a fiber composite part to form a preform is provided including determining a location having a longest stretch of continuous, unidirectional fibers in the part, determining an axis generally closest to and parallel to the fibers at the location, suspending the part from an anchor point within a heated cavity, heating the part to a temperature above a glass transition temperature and below a melting temperature of the resin of the part, and applying at least one force vector to the composite part, the sum of such vectors being parallel to the axis, wherein fibers of the part realign in a direction generally parallel to the sum of the force vectors, and wherein the composite part yields in the direction of the at least one applied force vector to provide a preform.

    Abstract: An ultrasonic manipulator (100) for processing three-dimensional composite preforms (124) is provided, including at least one end effector (102), the end effector having an ultrasonic cutting device (104), an ultrasonic machining device (106), an ultrasonic inspecting device (108), and an ultrasonic bonding device (110). A method for creating three-dimensional preforms for use in molding composite parts is also provided, and includes the steps of grasping a preform/ towpreg, inspecting the composite object using ultrasound, cutting a preform from the composite object using ultrasound, and at least some of the steps of shaping the preform using ultrasound, machining the preform using ultrasound, assembling a plurality of preforms, bonding the assembled preforms together to create a preform charge, and placing the preform charge in an injection mold.
