Abstract

L’invention concerne un procédé et une installation de réalisation d’une pièce composite. Le procédé comprend les étapes suivantes : a) on fournit une préforme composite (18) comportant une matrice polymère thermoplastique et des fibres de renfort, ladite préforme (18) présentant un bord (20) et une bordure (22) contiguë audit bord ; b) on fournit de l’énergie thermique à ladite préforme (18) ; c) on conforme ladite préforme (18) selon une conformation tridimensionnelle prédéterminée ; le procédé comprend en outre les sous- étapes suivantes : on fournit une bande (24) d’un matériau polymère thermoplastique à l’étape a) et on applique ladite bande (24) sur ladite bordure (22) avant l’étape b) de façon que l’énergie thermique porte ladite bande (24) dans un état visqueux à l’étape b) ; et, on moule ladite bande (24) visqueuse sur ledit bord (20) et ladite bordure (22) à l’étape c).The invention relates to a method and an installation for producing a composite part. The method comprises the following steps: a) providing a composite preform (18) comprising a thermoplastic polymer matrix and reinforcing fibers, said preform (18) having an edge (20) and a border (22) contiguous to said edge; b) supplying thermal energy to said preform (18); c) said preform (18) is shaped according to a predetermined three-dimensional conformation; the method further comprises the following sub-steps: providing a strip (24) of thermoplastic polymeric material in step a) and applying said strip (24) to said border (22) before step b) whereby the thermal energy brings said strip (24) into a viscous state in step b); and, molding said viscous strip (24) onto said edge (20) and said border (22) in step c).
