The present invention relates to a reinforcement blank (1, 6, 22, 23, 36) , in particular a curved ring frame segment for fuselage cells of aircraft, comprising a synthetic material that is reinforced by at least one fiber laminate (9, 25, 37) . The fiber laminate (9, 25, 37) includes at least one full area (10, 29, 39) with a first fiber direction and at least one full-area layer (11, 31, 40) with a second fiber direction, wherein at least one further layer (12, 34, 41) with a third fiber direction is arranged in a peripheral area (16, 26, 38) of the fiber laminate (9, 25, 37) . The invention also concerns a method for manufacturing the reinforcement beam (1, 6, 22, 23) , as well as a fiber laminate (9, 25, 37) , which is used to manufacture the inventive reinforcement beam (1, 6, 22, 23, 36) .
L~invention concerne une poutre de renfort (1, 6, 22, 23, 36), notamment un segment de couple incurvé pour des cellules de fuselage d~un aéronef, constituée d~une matière synthétique renforcée par au moins un stratifié de fibres (9, 25, 37). Le stratifié de fibres (9, 25, 37) comporte au moins une région complète (10, 29, 39) présentant une première direction de fibres et au moins une couche (11, 31, 40) dans la région complète présentant une deuxième direction de fibres. Au moins une couche supplémentaire (12, 34, 41) présentant une troisième direction de fibres est disposée dans une région périphérique (16, 26, 38) du stratifié de fibres (9, 25, 37). L~invention concerne également un procédé de fabrication de la poutre de renfort (1, 6, 22, 23), ainsi qu~un stratifié de fibres (9, 25, 37) utilisé pour fabriquer la poutre de renfort (1, 6, 22, 23, 36) de l~invention.
