Abstract:
A process for bonding a vented hollow component includes placing a preformed component with an aircraft skin on a tool surface, with bonding agent applied between the component and the skin. A vacuum bag is sealed about a vent in the preformed component. The vent may be formed through the vacuum bag and the component, or the vent may be preexisting (i. e. , an open end of the preformed component or an aperture through the component). The vacuum bag is sealed to the tool surface with a temporary seal or adhesive, to enclose the preformed component and the skin. A vacuum is applied within the bagging material, to compress the preformed component with the aircraft skin, and the bagged assembly is autoclaved to cure the bonding agent. The vent in the preformed component facilitates pressure equalization within and outside of the component to enhance compression against the aircraft skin.
