Title: METHOD FOR INFILTRATING A POROUS PREFORM
Abstract:
The invention relates to a method for infiltrating a porous preform with a molten metal, the infiltration being carried out in a furnace comprising a crucible that contains the molten metal, the method comprising: placing the porous preform in contact with the molten metal contained in the crucible (520), infiltrating the porous preform with the molten metal by capillarity (530), measuring the mass of the porous preform during infiltration (531), and separating the porous preform from the molten metal (540) when the measured preform mass reaches a predetermined value (532).
