Title (EN) METHOD AND APPARATUS FOR FORMING THICK COMPLEX SHAPED COMPOSITES
(FR) PROCEDE ET APPAREIL DE FORMAGE DE COMPOSITE EPAIS DE FORMES COMPLETES
Abstract:
(EN) A method and apparatus is disclosed for rapidly laying up and curing complex shaped resin matrix composites by rotating an alterable male mold (20) to wrap a plurality of continuous and intermittent layers of uncured laminate (40, 42, 44) around the male mold when in a closed position; allowing the male mold to be moved into a female mold (50) and to thereafter sever all layers on the male mold and articulate the male mold to an open position which shapes the upper regions of the composite thereafter transferring the resin matrix composite to a female mold which shapes the composite in a desired configuration and thereafter heat cures the composite lay-up material while being subjected to a vacuum. A second embodiment of the invention uses a non-rotatable male mold.
(FR) Procédé et appareil d'empilage et durcissement rapide de composites matriciels façonné complexes en résine, consistant à faire tourner un moule mâle modifiable (20) afin d'envelopper une pluralité de couches continues et discontinues de stratifié non durci (40, 42, 44) autour du moule mâle, lorsqu'il se trouve dans une position fermée; à faire se déplacer le moule mâle jusque dans un moule femelle (50), puis à séparer toutes les couches situées sur le moule mâle, à faire passer le moule mâle dans une position ouverte, laquelle façonne les régions supérieures du composite, ensuite, à transférer le composite matriciel en résine jusqu'à un moule femelle, lequel façonne le composite en une configuration voulue, et à durcir à chaud la matière empilée composite sous vide. Un second mode de réalisation de l'invention utilise un moule mâle non rotatif.
