METHOD FOR PRODUCING A ROTATIONALLY-MOLDED PLASTIC MATERIAL AND REINFORCING FIBERS THEREFOR ABSTRACT OF THE DISCLOSURE A substantially uniform layer of a fibre-reinforced plastic material is produced in a rotational Molding process by pretreating the fibres by at least partially coating them with a thermoplastic resin compatible with, having a melting point substantially not higher than the layer-forming plastic material and sinterable therewith, to produce discrete reinforcing fibres having the required integrity, length and strength for rotational molding, and then subjecting a substantially homogeneous blend of the pretreated fibres and the layer-forming plastic material to a rotational molding process whereby there is produced a layer of fibre reinforced plastic material having a substantially uniform distribution of fibres throughout the whole thickness of said layer. Pretreated reinforcing fibres for use in rotational molding to produce a substantially uniform layer of a fibre reinforced plastic material having a substantially uniform distribution of fibres throughout the whole thickness of said layer, and methods for effecting said pretreatment are also provided.
