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.

Composite panel comprising a metal foil and a polyolefine sheet

A process for the manufacture of shaped articles from compositions containing 30 to 70% by weight of polyolefine which is a high density polyethylene modified with polar monomers and 30 to 70% by weight of cellulosic fibres. These compositions are malaxated at a temperature at least 20.degree. C. above the melting point of the polyolefine. The process is applicable to the manufacture of panels which can be used in the automobile industry.

Process for the manufacture of articles from composition comprising

A laminated structure suitable for use for the interior decorating of buildings and for motor vehicle upholstery comprising at least one decorative layer of organic material, which is combined, by hot pressing, with a support consisting of a polyolefin sheet, in which the polyolefin sheet comprises from 10 to 90% by weight of cellulose fibres and from 90 to 10% by weight of a polyolefin which is modified by polar monomeric units derived from at least one monomer chosen from the group consisting of unsaturated carboxylic acids, the corresponding anhydrides and derivatives thereof.
