PROCEDE DE FABRICATION D'UNE PREFORME FIBREUSE CHARGEE DE PARTICULES CERAMIQUES REFRACTAIRES
The invention relates to a method for manufacturing a fibrous preform filled with refractive ceramic particles (20), comprising the following steps: a) placing a fibrous structure comprising refractive ceramic particles into a mould cavity (2) defined by a mould (3) and a counter mould (4; 4'), b) injecting a slip, comprising a powder that has refractive ceramic particles (20) and is present in a liquid medium, into the porosity of the fibrous structure (1) in the mould cavity (2), the injection being carried out at least through a first surface (1a) or a first edge (1a') of said fibrous structure (1), and c) draining, through a component (5) made of porous material, the liquid medium from the slip that has penetrated the fibrous structure (1), the component made of porous material having a thickness of greater than or equal to 0.1 mm, the drainage being carried out at least through a second surface (1b) or a second edge of the fibrous structure (1) that is different from the first surface (1a) or the first edge (1a'), said component (5) made of porous material further allowing the powder having refractive particles (20) to be retained in the porosity of the fibrous structure (1) in order to obtain a fibrous preform filled with refractive particles (20), the component (5) made of porous material being between the mould (3) and the fibrous structure (1) or between the counter mould (4; 4') and the fibrous structure (1), and the component (5) made of porous material being between at least one outlet vent (16) and the fibrous structure (1), pumping being carried out in the region of the outlet vent (16) in order to drain the liquid medium through said outlet vent (16).
L'invention concerne un procédé de fabrication d'une préforme fibreuse chargée de particules céramiques réfractaires (20) dans lequel une barbotine est injectée au travers d'une première face (1a) d'une texture fibreuse (1) et un drainage par une pièce en matériau poreux (5) est effectué au travers d'une deuxième face (lb) distincte de la première face, ladite pièce en matériau poreux (5) permettant en outre de retenir la poudre de particules réfractaires (20) dans la porosité de la texture fibreuse (1) afin d'obtenir une préforme fibreuse chargée de particules réfractaires (20).
