COEFFICIENT OF THERMAL EXPANSION CONTROL STRUCTURE
摘要
The present invention is directed to the incorporation of a substructure into tooling for constructing composite structures in order to control thermal expansion of the tooling during aerospace manufacturing processes. Substructure, such as headers and/or gussets is added to the tooling to constrain the growth of the laminate expansion and/or control the diametric growth of the tool during the curing cycle. The thickness of the face-sheet of the tooling also may be reduced in order to further reduce the effective coefficient of thermal expansion (CTE) of the tooling.
