Abstract

L'invention concerne un embout de connexion d'une conduite flexible (10) de transport de fluide. La conduite flexible (10) comprend au moins une gaine tubulaire (20) et au moins une couche (24, 25) d'amures de traction disposée extérieurement par rapport à la gaine tubulaire (20), la couche d'armures (24, 25) comprenant une pluralité d'éléments d'armure (29) filiformes. L'embout comporte au moins un tronçon d'extrémité de chaque élément d'armure, une voûte d'extrémité et un capot fixé sur la voûte d'extrémité, la voûte d'extrémité et le capot délimitant entre eux une chambre de réception de chaque tronçon d'extrémité, la chambre de réception étant remplie d'un matériau de remplissage. Le matériau de remplissage est une résine époxy comprenant des nanotubes de carbone liés chimiquement à la résine époxy. Un tel embout présente une reprise en tension axiale améliorée et un risque de défaillance en fatigue diminué.The invention relates to a connection end piece for a flexible pipe (10) for transporting fluid. The flexible pipe (10) comprises at least one tubular sheath (20) and at least one layer (24, 25) of tensile armor disposed externally with respect to the tubular sheath (20), the armor layer (24, 25) comprising a plurality of threadlike armor elements (29). The end piece comprises at least one end section of each armor element, an end vault and a cap fixed to the end vault, the end vault and the cap defining between them a chamber for receiving each end section, the receiving chamber being filled with a filling material. The filler material is an epoxy resin comprising carbon nanotubes chemically bonded to the epoxy resin. Such an end piece has improved axial tension recovery and a reduced risk of fatigue failure.
