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.
