Abstract

Noyau poreux modulaire pour le moulage de pièces à structure alvéolaire. Ce noyau est formé par plusieurs plaques empilées, chaque plaque étant une couche de volumes élémentaires ayant la même forme générale, préférentiellement sphérique. Lorsque les plaques sont empilées, ces volumes élémentaires sont imbriqués en empilement compact, de sorte qu'ils définissent entre eux des interstices dans lesquels le matériau à mouler s'infiltre lorsqu'il est à l'état fluide. Ce noyau est caractérisé en ce qu'il comporte au moins deux plaques de porosités différentes, de sorte que la structure alvéolaire de la pièce ainsi moulée comporte au moins deux zones de densités (et, subséquemment, de masses et de résistances) différentes. Procédé de fabrication, par moulage, d'un matériau solide à structure alvéolaire, utilisant un tel noyau.Modular porous core for molding parts with a honeycomb structure. This core is formed by several stacked plates, each plate being a layer of elementary volumes having the same general shape, preferably spherical. When the plates are stacked, these elementary volumes are nested in a compact stack, so that they define between them interstices into which the material to be molded infiltrates when it is in the fluid state. This core is characterized in that it comprises at least two plates of different porosities, so that the honeycomb structure of the part thus molded comprises at least two zones of different densities (and, subsequently, of masses and resistances). A method of manufacturing, by molding, a solid material with an alveolar structure, using such a core.
