Abstract
A vacuum debulking table for fiber reinforced thermoplastic prepreg includes a base, a base table mounted to the base, and a platen mounted to the base table. The platen has a frame and the base table includes a vacuum aperture located within the frame. A vacuum pump is connected to the vacuum aperture. The platen includes a heat generator. The table further includes tooling conforming to the frame and a kit to be debulked. A pair of opposing pressurized cylinders is coupled to the base at a first end. A top cover is mounted to the base and attached at a second end of the opposing pressurized cylinders. The top cover includes a flexible bladder. An insulator is mounted to the base table surrounding the platen. An insulation cover blanket is configured to be drawn between the insulator and top cover. An activation switch activates a programmable controller connected to the pressurized actuator control, the heat control and the vacuum control.
