摘要: A method for manufacturing deicing acoustic skin for an aircraft acoustic panel, using a fiber spacing device. The manufacturing method includes at least one step for manufacturing a layer assembly having a deicing layer supplied with electrically conductive fibers embedded in a resin and two insulating layers arranged on either side of the deicing layer, and a baking step. The method provides for fitting, during baking, a spacing device on the layer assembly, the spacing device having pins passing through said layer assembly, perforations being produced at the locations of the pins after the withdrawal of the spacing device, the fitting of the spacing device making it possible to produce perforations with desired sizes and shapes, in a simple and effective manner, and with a reduced manufacturing duration.

摘要: An acoustic panel for an aircraft nacelle includes a cellular layer configured to trap noise, a backplate fixed to one surface of the cellular layer and a facesheet fixed to another, opposite, surface of the cellular layer. The facesheet includes a layer of a preimpregnated woven material containing weft yarns spaced apart from one another and warp yarns spaced apart from one another so that the facesheet exhibits openings between the yarns.

摘要: A process for manufacturing an acoustic panel including at least one acoustically resistive layer, at least one cellular structure and a reflective wall. The process includes steps of depositing the parts of the acoustic panel made of thermosetting composite, depositing a film made of thermoplastic resin that is miscible with the thermosetting composite at the polymerization temperature of the thermosetting composite, polymerizing the parts of the acoustic panel made of thermosetting composite, and depositing and consolidating at least one layer made of thermoplastic composite against the film made of thermoplastic resin in order to form the reflective wall.

摘要: A structure made of composite material for a propulsive aircraft assembly includes at least one thermal zone designed to receive electrical energy. Each thermal zone includes at least one resistive skin having an inner film produced in a thermoplastic material made conductive by the inclusion of carbon nanotubes, such that each resistive skin is designed to dissipate, by Joule effect, at least a portion of the electrical energy received by the thermal zone, an intermediate ply produced in a satin fabric impregnated with a thermoplastic material, and an outer film produced in a thermoplastic material.
