METHOD FOR THE MANUFACTURING OF A STIFFENED STRUCTURAL COMPONENT MADE OF COMPOSITE MATERIAL AND STRUCTURAL COMPONENT
A method for manufacturing a structural component is disclosed. The structural component comprises a skin formed by layers of composite material, stringers made of a composite material fixed to the skin and ribs made of a composite material fixed to the skin, the structural component has sub-panels joined to one another and each comprising a sub-skin defined by first layers of composite material, at least one stringer and at least one rib fixed to an internal surface of the sub-skin, wherein the structural component comprises a continuous sub-wall defined by the union of the external surfaces of the sub-skins of the sub-panels joined to one another, second layers of composite material are laminated on the first layers so as to define a continuous external over-skin layered on said sub-wall, wherein the skin is defined by the set of said sub-skins and over-skins and consists of the first and second layers.
Port, dispensing system comprising such a port, and manufacturing method
A port is suitable for attachment to a container and suitable for being traversed by a needle used to transfer content between the inside of the container and the outside of the container, and includes a rigid annular body extending in a direction including a side wall surrounding a channel extending between an inner end and an outer end, the inner and outer ends being at opposite ends along the direction, the body being open at the ends, an overmolding member of thermoplastic elastomer including a sealing portion suitable for being traversed by the needle in a direction close to the direction, the needle passing through the inner and outer ends, the overmolding member sealing the channel in a fluidtight manner after withdrawal of a needle and further including an adhesion portion suitable for attaching the port to the container.

COMPOSITE VANE FOR AN AIRCRAFT TURBOMACHINE FAN COMPRISING MEANS FOR MEASURING INTERNAL DEFORMATIONS
A blade made of a composite material for an aircraft turbomachine fan, the blade comprising means for measuring internal deformations of the blade and means for remotely storing and transmitting signals for measuring the deformation of the blade, which means are connected to the measuring means, the measuring means and the remote storage and transmission means being located in the composite material. The means for measuring can be configured to supply the means for remotely storing and transmitting.
Method for manufacturing high-pressure tank and high-pressure tank
A method for manufacturing a high-pressure tank includes: forming a preform by winding a carbon fiber around a liner to form a fiber layer on an outer periphery of the liner, and impregnating the fiber layer of the preform with a curable resin and curing the curable resin. When winding the carbon fiber around the liner, a metal wire together with the carbon fiber is wound around the liner.
Method for manufacturing by molding elongate and hollow workpieces made from composite material, molding device for implementing the method and workpieces obtained
The method includes producing an initial preform on a mandrel by filament winding without generating shrinking, cutting the initial preform to the correct length, placing the assembly provided beforehand with internal drainage device and pressurization device into a female mold, and bringing the preform assembly to a softening temperature and pressurizing the assembly at both ends until it is deformed by a diametrical increase in its dimensions. The method further includes bringing the impregnation resin to polymerization temperature and pressure in order to allow the workpiece to consolidate, its external shape becoming consistent with the internal shape of the mold, opening the mold and removing the workpiece from the mold, and machining the final shapes of the composite workpiece.
