The invention relates to a composite panel comprising at least one metal foil combined, by hot pressing, with at least one polyolefine sheet in which the polyolefine sheet is produced from a mixture of 10 to 90% by weight of cellulose fibres and from 90 to 10% by weight of a polyolefine modified by polar monomer units derived from at least one monomer selected from the group consisting of the unsaturated carboxylic acids, the corresponding anhydrides and their derivatives. The presence of cellulose fibres in the polyolefine improves the adhesion between the components of the composite panel.

Fibrils made of synthetic polymer and which are in the presence of vapors of an organic solvent are recovered in a closed chamber containing a liquid for suspending the fibrils and a gaseous atmosphere. The chamber contains means for introducing the fibrils and solvent vapors into the closed chamber, means for discharging the solvent vapors from the closed chamber, means for introducing into the closed chamber liquid for suspending the fibrils, and means for withdrawing the suspension of fibrils from the closed chamber.
