Abstract
A method for manufacturing a part made of composite material, includes the arrangement of a fibrous preform in the impregnation chamber of a mold, the impregnation chamber being closed by a flexible membrane separating the impregnation chamber from a compaction chamber, an impregnation fluid being injected into the impregnation chamber and a compression fluid being injected into the compaction chamber, the compression fluid being a liquid in which the value of the density is between 60% and 125% of the density of the impregnation fluid.
Claims13
A method for manufacturing a part made of composite material comprising steps:
- arrangement of a fibrous preform in a mold comprising an impregnation chamber being in contact with a first face of the preform on a support surface of the impregnation chamber, the impregnation chamber being closed by a flexible membrane placed facing a second face of the preform opposite the first face, said membrane separating the impregnation chamber from a compaction chamber,
- injection of a compression fluid into the compaction chamber and injection of an impregnation fluid comprising a matrix precursor into the impregnation chamber,
- solidification treatment of the matrix precursor within the fibrous preform so as to obtain a part made of composite material comprising a fibrous reinforcement bound by a solid matrix,
- wherein the compression fluid is a liquid in which a value of a density corresponds to between 60% and 125% of a value of a density the impregnation fluid.
