Abstract
A method and apparatus for manufacturing composite parts. An expandable tool with a transfer system may be moved on a surface of the expandable tool into an outer mold line tool with a composite material laid up on the outer mold line tool. The expandable tool may be expanded in the outer mold line tool to change the surface from a retracted state to an expanded state. The transfer system may be transferred from the expandable tool with the surface in the expanded state to the outer mold line tool.
