Abstract
Elément pour une turbomachine d’aéronef, comportant : - une paroi (10) en matériau composite, - un seuil de renfort (18) appliqué sur une surface (10b) de la paroi et comportant au moins un second orifice (26) aligné avec un premier orifice (22) de la paroi, et - au moins un insert taraudé (20) de fixation qui est engagé dans les premier et second orifices, cet insert comportant un corps (20a) dont une extrémité est reliée à une tête (20b) engagée dans un renfoncement (24) de la première surface (10a), et dont une extrémité opposée comprend un trou taraudé (28), caractérisé en ce que le corps de l’insert traverse le second orifice et coopère par complémentarité de formes avec cet orifice de façon à bloquer en rotation l’insert dans cet orifice. Figure pour l'abrégé : 4
