Abstract
An apparatus and methods for forming a composite part are provided. A method for forming a composite part may include placing initial composite material on a base tool, placing a tooling mandrel on the composite material, placing additional composite material over the tooling mandrel, covering at least a portion of the composite material that overlays the tooling mandrel with a composite forming tool, heating the composite material to at least partially cure the composite material, and permitting a first portion of the composite forming tool to change size during the heating of the composite material to a greater degree than a second portion of the composite forming tool. In this regard, the second portion of the composite forming tool is closer to the base tool than the first portion of the composite forming tool. A composite forming tool is provided that permits differential expansion of different portions of the tool.
