摘要： A method of fabricating a composite material casing of varying thickness for a gas turbine includes using three-dimensional or multilayer weaving to make a fiber texture in the form of a strip; winding the fiber texture as a plurality of superposed layers onto a mandrel of profile corresponding to the profile of the casing to be fabricated, so as to obtain a fiber preform of shape corresponding to the shape of the casing to be fabricated; and densifying the fiber preform with a matrix. During winding of the fiber texture on the mandrel, a textile strip is interposed between the adjacent turns of the fiber texture, the textile strip presenting a width that is less than the width of the fiber texture and defining a retention zone of the casing.

摘要： A process for manufacturing a composite material component including a fiber reinforcement based on carbon fibers densified by a matrix, includes successively producing a fiber structure by multilayer three-dimensional weaving, placing the fiber structure in a closed mold, and injecting a resin into the mold, and wherein, during the weaving of the fiber structure, the process further includes spraying carbon nanoparticles onto the carbon fibers.

摘要： There is provided a method of fabricating a blade platform out of composite material with integrated gaskets for a turbine engine fan, the platform including a base and a stiffener, the method including using three-dimensional weaving to make a single-piece fiber blank with a plurality of longitudinal yarn layers extending in a direction corresponding to a longitudinal direction of the base of the platform; shaping the fiber blank to form a fiber preform having a first portion forming a base preform and a second portion forming a stiffener preform; positioning platform gaskets at side margins of the first portion of the fiber preform forming a base preform; placing the fiber preform with the gaskets in an injection mold; injecting resin into the injection mold; compacting the assembly; heating the injection mold to solidify the resin; and unmolding the resulting platform.

摘要： A method of simulating shaping a textile strip by winding on a mold presenting a surface of revolution is described. The textile strip is made by three-dimensional weaving between a plurality of layers of warp yarns and a plurality of layers of weft yarns, the warp yarn layers being interlinked by the weft yarn layers. For each warp yarn layer, the method includes positioning crossing points between at least some of the warp yarns of the warp yarn layer and at least some of the weft yarns, the warp yarns of the at least some of the warp yarns including a reference warp yarn having a determined axial position on the mold.

摘要： A three-dimensional fibrous preform of a fan blade includes a blade root and a blade airfoil between the blade root and a free end of the preform. The airfoil has an area with two skins and a longitudinal stiffener between the skins and, in a transverse plane, transverse yarns of the skins woven in pairs in the first and in the second skin either side of the stiffener, the yarns of a first pair of the first skin are separated into two unit yarns at the stiffener, the unit yarns being woven separately with longitudinal yarns, the yarns of a second pair of the second skin are separated into two unit yarns at the stiffener, the yarns being woven separately with longitudinal yarns, and a yarn of each pair cross over each other twice in the stiffener.

摘要： A fibrous preform obtained by three-dimensional weaving, comprising a first skin, a second skin, and a central portion connecting them and forming a stiffening element. In a transverse plane, transverse threads of the first skin and the second skin are woven in pairs in the first skin and the second skin on either side of the central portion; the threads of a first pair of the first skin and of a second pair of the second skin are separated into two unitary threads at the central portion by being woven with longitudinal threads, and a thread of the first pair crosses a thread of the second pair at least twice in the central portion.
