Summary: | A method for impregnating a fibrous preform by injection or infusion, comprising steps of: -providing a mold having at least two portions, said mold presenting an inlet orifice and a vent orifice placed on opposite sides of the mold; -placing a fibrous preform in a portion of the mold; -placing a thermo-expandable seal in a passage formed between an inside wall of the mold and the fibrous preform, said passage extending substantially along the direction (X) extending between the opposite sides of the mold; -closing the mold; -heating the mold so that the thermo-expandable seal expands and shuts off said passage; and-impregnating the fibrous preform with an impregnation material. |
