A process for producing a thermoformable fibre-plastics composite product comprising lignolcellulosic or natural fibres, particularly but not exclusively useful as an intermediate product in subsequent manufacture, comprises conveying the fibres in a dry or wet air stream and applying to the fibres a thermoplastic binding agent, and forming the fibres into a solid or semi-solid product such as a panel, which is thermoformable. In at least a preferred embodiment the process may be carried out in known plant for manufacture of medium density fibre board.
L~invention concerne un procédé pour la production d~un produit composite fibres-plastique thermoformable comprenant des fibres lignocellulosiques ou naturelles, qui sont en particulier mais non exclusivement utiles en tant que produit intermédiaire pour une fabrication ultérieure. Ce procédé consiste à transporter les fibres dans un courant d~air humide ou sec et à appliquer aux fibres un agent de liaison thermoplastique et à former les fibres en un produit solide ou semi-solide tel un panneau qui soit thermoformable. Dans au moins un mode de réalisation préféré, le procédé peut être réalisée à partir d~une plante connue pour la fabrication d~un panneau de fibres de densité moyenne.
