Abstract

L’invention concerne un système de renforcement (22) destiné à équiper un carter de soufflante (8) pour une turbomachine, le carter de soufflante (8), réalisé dans un matériau composite avec un renfort fibreux et une matrice, comprenant une paroi (20) généralement cylindrique d’axe longitudinal X et au moins une bride de fixation (21a, 21b), annulaire, s’étendant radialement en formant une zone de jonction (17). Selon l’invention, le système de renforcement comprend au moins une embase (23) s’étendant au moins en partie suivant une direction circonférentielle autour de l’axe longitudinal X, l’embase présentant une première surface de contact (24a) de forme complémentaire avec une surface radiale (25) de la bride de fixation (21a, 21b) et un côté (26a) destiné à épouser la zone de jonction (17), et au moins un organe de renfort (30) qui comporte une semelle (31) s’étendant depuis l’embase suivant l’axe longitudinal, la semelle présentant une deuxième surface de contact (32) de forme complémentaire avec une surface radialement externe (27) de la paroi cylindrique. Figure pour l’abrégé : Figure  4The invention relates to a reinforcement system (22) intended to equip a fan casing (8) for a turbomachine, the fan casing (8), made of a composite material with a fibrous reinforcement and a matrix, comprising a wall ( 20) generally cylindrical with longitudinal axis X and at least one fixing flange (21a, 21b), annular, extending radially forming a junction zone (17). According to the invention, the reinforcement system comprises at least one base (23) extending at least partly in a circumferential direction around the longitudinal axis complementary with a radial surface (25) of the fixing flange (21a, 21b) and a side (26a) intended to match the junction zone (17), and at least one reinforcing member (30) which comprises a sole ( 31) extending from the base along the longitudinal axis, the sole having a second contact surface (32) of complementary shape with a radially external surface (27) of the cylindrical wall.
