Title (EN) A STRUCTURAL LONGITUDINAL COMPOSITE JOINT FOR AIRCRAFT STRUCTURE
(FR) JOINT COMPOSITE LONGITUDINAL STRUCTURAL POUR STRUCTURE D'AVION
Abstract:
(EN) The present invention regards a structural composite part made of pre-impregnated fibre plies (5). The edges (7) of two adjacent fibre plies (5) are connected via a longitudinal composite joint (9) made structural by a nanostructure (41) arranged within the composite joint (9). The invention concerns also a method of producing a structural composite part (11) made of pre-impregnated fibre plies wherein the edges (7) of two adjacent fibre plies (5) are connected via a longitudinal composite joint (9) made structural by a nanostructure (41) and an aircraft structure, such as a wing, comprising such structural composite parts (11).
(FR) La présente invention concerne une pièce composite structurale composée de couches de fibres pré-imprégnées (5). Les bords (7) de deux couches de fibres adjacentes (5) sont reliés par le biais d'un joint composite longitudinal (9) rendu structural par une nanostructure (41) disposée dans le joint composite (9). L'invention se rapporte également à un procédé de production d'une pièce composite structurale (11) composée de couches de fibres pré-imprégnées, les bords (7) de deux couches de fibres adjacentes (5) étant reliés par le biais d'un joint composite longitudinal (9) rendu structural par une nanostructure (41), et à une structure d'avion, telle qu'une aile, comprenant de telles pièces composites structurales (11).
