Abstract

L'invention concerne un procédé de drapage d'au moins un pli fibreux (100) pré-imprégné d'un précurseur d'une matrice sur un outillage de mise en forme (200) comprenant une face principale (210) et des première et deuxième faces latérales (220, 230) s'étendant perpendiculairement les unes par rapport aux autres et se réunissant en un coin de valise (240). Chaque pli comporte un premier bord (111) s'étendant suivant une première direction (A) et un deuxième bord (112) s'étendant suivant une deuxième direction (B) perpendiculaire à la première direction (A), les premier et deuxième bords (111, 112) étant respectivement plaqués sur les première et deuxième faces latérales (220, 230) de l'outillage de mis en forme en déformant une portion de jonction (120) entre lesdits bords sur le coin de valise (240). Chaque pli comprend une portion de sur-longueur (130) s'étendant le long d'une partie des premier et deuxième bords (111, 112) au niveau de leur portion de jonction (120), une ou plusieurs forces de tractions (FT1) étant exercés sur la portion de sur-longueur lors de la déformation de la portion de jonction (120) sur le coin de valise (240).The invention relates to a method of draping at least one fibrous ply (100) pre-impregnated with a precursor of a matrix on a forming tool (200) comprising a main face (210) and first and second side faces (220, 230) extending perpendicular to each other and meeting in a suitcase corner (240). Each fold has a first edge (111) extending in a first direction (A) and a second edge (112) extending in a second direction (B) perpendicular to the first direction (A), the first and second edges (111, 112) being respectively pressed on the first and second lateral faces (220, 230) of the shaping tool by deforming a junction portion (120) between said edges on the corner of the case (240). Each ply includes an over-length portion (130) extending along a portion of the first and second edges (111, 112) at their junction portion (120), one or more tensile forces (FT1 ) being exerted on the excess length portion during the deformation of the junction portion (120) on the case corner (240).
