Patent ID: 8012389

Claim:
A process for producing a thermoformable fibre-plastics composite product comprising fibres of a lignocellulosic material or natural fibres, comprising: conveying loose or divided fibres or fibre bundles, produced by mechanically or thermomechanically or chemo-thermomechanically or chemo-mechanically breaking down a lignocellulosic material, or natural fibres, in a dry or wet air stream and applying to or intimately mixing with the fibres while so conveying the fibres sufficient of one or more thermoplastic binding agents in a liquid formulation or particulate form to enable, after subsequently forming the fibres into a solid panel, said panel to be thermoformed to a different shape, and so forming the fibres into a solid thermoformable panel having a density of about 500 kg/m 3 or more by hot pressing the fibers.
