Abstract

Grille composite (1) d’inverseur de poussée, comportant au moins une paroi longitudinale (15) et des parois transversales (14) se raccordant à cette paroi longitudinale, caractérisée par le fait que la paroi longitudinale comporte au moins un faisceau de fibres continu longitudinal (19) et les parois transversales chacune au moins un faisceau de fibres continu transversal (23) croisant le faisceau longitudinal, de sorte que les intersections (16) des parois transversales et longitudinales soient structuralement pontées dans les deux directions par les faisceaux de fibres continus longitudinal et transversal de renfort.
