Abstract
A system for forming a composite component includes a close mold tool defining a cavity that corresponds to a shape of the composite component and configured to receive a composite material. The system further includes a perforated release film defining a plurality of openings and configured to be positioned on a surface of the composite material within the cavity. The system further includes a breather configured to be positioned on the perforated release film, to allow a vacuum to be applied to the composite material through the breather and the plurality of openings, and to allow pressurized fluid to be applied to the perforated release film through the breather.
