Abstract: The invention relates to a novel electric powder impregnation process for impregnating powder into a fibrous, filamentary and/or porous network, especially in order to produce a composite, comprising a continuous, rigid or flexible, matrix with which said network is in intimate contact, in which process the powder on the one hand and said network on the other are placed between a lower electrode and an upper electrode, these electrodes are electrically insulated from each other by a dielectric and connected to the respective poles of an AC generator so as to simultaneously subject the powder and said network to an electric field, characterized in that the upper electrode comprises at least one electrode tube and the AC electric field applied is from 0.10 to 20 kV/mm.
