Abstract: A flexible pipe designed to transport fluids that include, from the interior toward the exterior: an internal tubular sheath with an axis (A-A?) defining an internal passage for fluid circulation; a composite reinforcing structure applied around the tubular sheath and connected to the tubular sheath; at least one sealing layer made of thermoplastic material applied around the composite reinforcing structure; at least one ply of tensile armor, not connected to the sealing layer, the at least one ply of tensile armor ply comprising at least one armor element wound around the sealing layer; the thickness of the sealing layer being less than 15 mm.

Abstract: A composite armour for a flexible pipe includes a composite profile and a reinforcement tape. The composite profile includes longitudinally oriented reinforcement fibres embedded in a polymer matrix. The reinforcement tape includes a woven tape comprising fibres impregnated with a polymer material, in such a way that the weft thread of the reinforcement tape is orthogonal to the longitudinal direction of the profile, and the warp thread is parallel to the longitudinal direction of the profile.

Abstract: The present invention relates to a flexible pipe comprising a mechanical reinforcement element (4) and a pressure sheath. Mechanical reinforcement element (4) comprises at least one metallic tensile armour layer (6) and at least one composite tensile armour layer (7). Composite tensile armour layer (7) is arranged outside metallic tensile armour layer (6). Separation means (8) are provided to separate composite tensile armours (7), while maintaining a radial clearance and a circumferential clearance for composite tensile armours (7).

Abstract: The invention relates to a blade made of composite material, provided with a reinforcement (17) made of a stronger material with regard to a leading edge (5) likely to be struck by solid objects, which comprises, under the aerodynamic portion of the blade, extensions (18, 19) attached to the blade root. According to the invention, the extensions (18, 19) are dissymmetric, the extension (18) located on the suction side being generally further back from the leading edge (5) than the extension (19) on the pressure side.

Abstract: A pipe (10) for conveying a fluid, including an inner sheath (20), at least one layer (34, 36) of inner armors, arranged outside the inner sheath (20) and an outer protection sheath (22), positioned outside each layer (34, 36) of inner armors. It includes an inner fluid, received between the inner sheath (20) and the outer sheath (22). The pipe includes an intermediate polymer sheath (24), interposed between the inner sheath (20) and the outer sheath (22), the intermediate sheath (24) and the inner sheath (20) delimiting an inner annular space (26) between them for receiving the inner fluid. The inner fluid is confined in the inner annular space (26) at a pressure above 50 bars.
