Abstract
A method for impregnating a fibrous preform by injection or infusion, the method including the 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 seal in a passage formed between an inside wall of the mold and the fibrous preform, said passage extending substantially along the direction extending between the opposite sides of the mold; closing the mold so that the two portions of the mold co-operate with the seal in such a manner as to shut off said passage; and impregnating the fibrous preform with an impregnation material.
