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.

L'invention concerne l'incorporation d'une sous-structure dans un outillage destiné à construire des structures composites afin de commander la dilatation thermique de l'outillage pendant des processus de fabrication aérospatiaux. Une sous-structure, telle que des collecteurs et/ou des goussets, est ajoutée à l'outillage pour limiter la croissance de la dilatation laminaire et/ou commander la croissance diamétrique de l'outil pendant le cycle de durcissement. L'épaisseur de la feuille de face de l'outillage peut aussi être réduite afin de réduire encore le coefficient effectif de dilatation thermique (CTE) de l'outillage.
