ABSTRACT:
A specially constructed multilayer fibre mat is made up of two cover layers of fibres with a high-quality thermosetting plastics impregnation and a central layer of if necessary short-fibre wood products with more particularly cheap thermoplastic bonding agent additives. In that construction and that composition the mats offer special possible applications for mouldings in the motor car industry, both as regards their manufacturing process and also the quality of the end product itself.
