Original Abstract Submitted
a method for forming composite parts includes loading an uncured composite material into a middle cavity of a chamber between an upper membrane and a lower membrane, wherein a lower cavity is defined below the lower membrane, and wherein an upper cavity is defined above the upper membrane, wherein a forming tool is disposed within the upper cavity. a vacuum is applied to the upper cavity, the middle cavity, and the lower cavity to remove at least a portion of gas entrapped within the uncured composite material. the vacuum is released from the upper cavity and the lower cavity, and the chamber is heated to a forming temperature of the uncured composite material. pressure is controlled in the upper cavity and the lower cavity to form the heated composite material, wherein a greater pressure is applied to the lower cavity than to the upper cavity such that a pressure differential between the lower cavity and the upper cavity causes the heated composite material to form around the forming tool. the chamber is heated to a curing temperature to cure the heated composite material.
