Abstract

See full text

A tooling mandrel for manufacturing a composite structure may include a mandrel body having a fluid passage network formed within the mandrel body for passing a fluid medium through the mandrel body. The fluid passage network may have a passage cross-sectional area shaped to promote thermal conductance between the fluid medium and the tooling mandrel and cause a change in a mandrel cross-sectional shape.
