A method and associated apparatus for forming a composite structural member from a charge are provided. The charge can be disposed on a first die of the apparatus and formed to a desired configuration defined by a recess of the die by inserting a second die or a tool into the recess. In some cases, the first die can include two portions that are adjustable in a transverse direction so that the recess can be opened by the insertion of the second die or tool. The second die or tool can be a substantially rigid member or an inflatable bladder. In either case, the charge can be disposed on the first die, formed, and then further processed on the first die, thereby facilitating indexing of the charge for each operation.

L'invention concerne un procédé et un appareil associé permettant de former un élément structurel composite à partir d'une charge. Celle-ci peut être disposée sur une première matrice de l'appareil et formée selon une conception recherchée définie par un évidement de la matrice, par insertion d'une seconde matrice ou d'un outil dans l'évidement. Dans quelques cas, la première matrice peut comprendre deux parties réglables dans une direction transversale de manière que l'évidement puisse être ouvert par insertion de la seconde matrice ou de l'outil. La seconde matrice ou l'outil peut être un élément sensiblement rigide ou une vessie gonflable. Dans les deux cas, la charge peut être disposée sur la première matrice, formée, puis traitée sur la première matrice, facilitant ainsi l'indexage de la charge pour chaque opération.
