The invention relates to a method for producing a composite object consisting at least of two distinct parts having different properties and/ or functions. Said method consists in forming at least one layer (53) containing more than 70 % by weight of expanded material selected from expanded graphites, in forming at least one other layer (53) containing more than 70 % by weight of another expanded material selected from expanded vermiculites, in compressing the thus formed layers in such a way that said layers are consolidated, each layer corresponding to one part of the object. The inventive method makes it possible, in particular to produce composite objects such as electrochemical cells, a casting mould or a heliothermal converter.
L'invention concerne un procédé de fabrication d'un objet composite comprenant au moins deux parties distinctes ayant des propriétés et/ou fonctions différentes, caractérisé en ce qu'on forme au moins une épaisseur (53) comprenant plus de 70 % en poids d'un matériau expansé choisi parmi les graphites expansés, on forme au moins une autre épaisseur (52) comprenant plus de 70 % en poids d'un autre matériau expansé choisi parmi les vermiculites expansées, puis on comprime ensemble les épaisseurs formées de façon à les consolider, chaque épaisseur consolidée correspondant à l'une des parties de l'objet. Le procédé permet notamment de réaliser des objets composites tels qu'une cellule électrochimique, un moule de fonderie ou encore un convertisseur héliothermique.
