Abstract: A system for manufacturing a composite part from composite material comprises a bag and a tool. The bag may retain a first portion of the composite material and may include a chamber and a sheet, to which the chamber is coupled. The chamber may be positioned adjacent a rigidized support configured to maintain the chamber in the shape of a non-planar feature of the composite part. The tool may include an upper surface configured to retain a second portion of the composite material and shaped to correspond to an outer mold line of the composite part. The bag may be placed upon the upper surface of the tool such that the composite material is fully enclosed by the combination of the bag and the upper surface of the tool. A heating element may provide a high temperature to cure the composite material.
