Title: METHOD FOR MANUFACTURING A COMPONENT MADE OF COMPOSITE WITH IMPROVED INTRA-FILAMENT DENSIFICATION
Abstract:
Method for producing a component made of composite comprising a fibrous reinforcement that is densified with a matrix, said method involving the following steps: - creation of a fibrous texture (10) by weaving filaments, said fibrous texture having a determined initial mean fibre content, - densification of the fibrous texture using a matrix. According to the invention, the fibrous texture (10) is, prior to densification, subjected to one or more jets (120) of water under pressure so as to reduce the mean fibre content in the texture to a value of between 20% and 45%.
