Abstract
An example apparatus for fabrication of a co-cured composite assembly includes a layup tool body with a cavity, a thermal expansion insert inserted into the cavity of the layup tool body and a first uncured composite part of the composite assembly is positioned onto the thermal expansion insert, and a solid internal mandrel configured for insertion onto the first uncured composite part. During curing, the first uncured composite part compacts and reduces in thickness while the solid internal mandrel and the thermal expansion insert each increase in size to apply pressure to the first uncured composite part.
