Abstract

Procédé de fabrication d'une préforme de grille , procédé de fabrication d’une grille en matériau composite, préforme de grille et grille en matériau composite Un procédé de fabrication d'une préforme de grille comprend : - la formation par tissage tridimensionnel d'une pluralité d’ébauches fibreuses chacune séparée dans son épaisseur en des première, deuxième et troisième parties dans trois zones de déliaison décalées les unes des autres, la première partie étant située entre la deuxième partie et la troisième partie, - la formation, à partir de chaque ébauche fibreuse, d'une préforme en épi (130), par dépliage de part et d'autre de la première partie des segments (104a, 108a, 110a) de la deuxième partie et des segments (107a, 109a, 111a) de la troisième partie non liés à la première partie, et par la mise en forme des segments (104a, 108a, 110a, 107a, 109a, 111a) dépliés pour former des premières branches (131, 132, 133) et des deuxièmes branches (134, 135, 136), - l’assemblage des préformes en épi (130) de manière à former une préforme de grille.
