Abstract
An ultrasonic manipulator for processing three-dimensional composite preforms is provided, including at least one end effector, the end effector having an ultrasonic cutting device, an ultrasonic machining device, an ultrasonic inspecting device, and an ultrasonic bonding device. 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.
