Abstract

L'invention concerne une structure de fibres, qui comprend un corps stratifié (20) et une lisière (40). Le corps stratifié (20) comprend : au moins une couche de chaîne (21) qui a une pluralité de fils de chaîne (23) s'étendant dans une première direction (X) ; et au moins deux couches de trame (22) qui ont chacune une pluralité de fils de trame (24) s'étendant dans une seconde direction (Y). Dans une section d'extrémité (20a) du corps stratifié (20), le fil de lisière (40) est entrelacé avec les fils de trame (24) de couches de trame (22) positionnés aux deux extrémités dans une direction de stratification (Z). Certains fils de chaîne (23) servent de fils de liaison pour lier la couche de chaîne (21) et les couches de trame (22). La lisière (40) est un fil continu. Les fils de trame (24) des couches de trame (22) positionnés aux deux extrémités dans la direction de stratification (Z) sont un filé.
