Abstract

L’invention concerne un procédé de fabrication d’au moins une pièce (1) et d’au moins une éprouvette de caractérisation d’une telle pièce (1), caractérisé en ce qu’il comporte les étapes consistant à placer au moins une préforme tissée dans un moule, ladite préforme étant destinée à former un renfort fibreux de la pièce (1), placer au moins un renfort principal (9) dans ledit moule au niveau d’au moins une zone principale (2) de la préforme, placer au moins un renfort auxiliaire (10) au niveau d’au moins une zone auxiliaire de la préforme destinée à former une zone de rebut (8) de la pièce (1), insérer une résine dans ledit moule, ladite résine étant destinée à former une matrice, chauffer le moule de façon à polymériser ladite résine et à former ladite pièce (1), séparer au moins une zone de rebut (8) de la pièce (1). Figure à publier avec l’abrégé : [Fig. 3]The invention relates to a method of manufacturing at least one part (1) and at least one test piece for characterizing such a part (1), characterized in that it comprises the steps consisting of placing at least one preform woven in a mold, said preform being intended to form a fibrous reinforcement of the part (1), placing at least one main reinforcement (9) in said mold at least one main zone (2) of the preform, place at least one auxiliary reinforcement (10) at least one auxiliary zone of the preform intended to form a waste zone (8) of the part (1), insert a resin into said mold, said resin being intended to form a matrix, heat the mold so as to polymerize said resin and form said part (1), separate at least one waste zone (8) from the part (1). Figure to be published with the abstract: [Fig. 3]
