AI Technical Summary

Problems solved by technology

However, this possibility is limited by the fact that it requires a complete characterization of the fabricated composite, which proves to be time-consuming and expensive
Furthermore, such characterization of composites is often done at the expense of other properties of the resin (heat resistance, etc.)

Embodiment Construction

[0020] The invention relates to a method for producing a composite material component, in particular a turbine engine component, such as a fan blade, comprising a fiber reinforcement based on carbon fibers densified by an organic matrix.

[0021] In a known manner, such a method consists in turn of producing a fiber structure by multilayer three-dimensional weaving, placing the fiber structure in a closed mold, and injecting resin into the mold, characterized in that during the weaving of the fiber structure.

[0022] As used herein, "three-dimensional (3D) weaving" is understood to mean a multi-layer weaving using several layers of weft threads and several layers of warp threads, wherein the warp threads interconnect the weft threads of different layers. Different types of 3D weave patterns can be used, such as interlocking, multi-satin, multi-weave, multi-twill weaves. Reference may be made in particular to document WO 2006 / 136755, the content of which is incorporated herein...

Abstract

The present invention relates to a method for manufacturing a composite part comprising fiber reinforcement based on carbon fibers densified by a matrix, the method comprising, in sequence, 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 the resin is bonded to the fiber structure by means of the multilayer three-dimensional weaving. During weaving of the fibrous structure, the method further includes spraying carbon nanoparticles onto the carbon fibers. The invention also relates to a device for carrying out such a method.

Description

technical field [0001] The invention relates to the manufacture of components made of composite material comprising fiber reinforcement based on carbon fibers densified by a matrix. [0002] More precisely, the invention relates to the manufacture of composite components for turbomachinery from fiber structures obtained by three-dimensional weaving of carbon fibers and densified by a reinforcing matrix. Background technique [0003] It has been proposed to produce composite parts for turbomachinery, such as blades for gas turbine engines. For example, reference may be made to document EP 1 526 285 which describes the production of fiber preforms by three-dimensional (3D) weaving and the densification of the preforms with an organic matrix for the manufacture of wind turbine blades. [0004] As used herein, "3D weaving" is understood to mean a multilayer weaving using several layers of weft threads and several layers of warp threads, wherein the warp threads interconnect dif...
