Abstract
A method for ultrasonic debulking a composite laminate includes the steps of defining a path across the laminate, the path having a starting location and an ending location and applying a force to and transmitting ultrasonic vibration into the laminate along the path, beginning at the starting location and ending at the ending location. The method further includes determining a temperature of a surface of the laminate proximate to the path and varying at least one of an amplitude of the ultrasonic vibration, the applied force, a feed rate at which the force and the ultrasonic vibration are applied along the path, an angle at which the ultrasonic vibration is applied to the laminate, and an interval at which plies of the laminate are processed, based upon the determined temperature of the surface of the laminate.
