Abstract

A method of impregnating a fiber preform with an impregnation composition, includes applying a liquid on a structure, the structure including a chamber in which a fiber preform for impregnating is present, the chamber being defined between a rigid support on which the fiber preform is placed and a wall, the wall having a face situated facing the fiber preform; and an impregnation composition for impregnating the fiber preform, the impregnation composition being present in the chamber; the liquid being applied against the wall on its side opposite from the chamber, the wall being configured so that its face situated facing the fiber preform conserves its shape during the application of the liquid, the applied liquid enabling sufficient pressure to be created to move the wall towards the rigid support and impregnate the fiber preform with the impregnation composition.
