Abstract
A process for the continuous preparation of a coated, long fiber reinforcing composite structure suitable for the preparation of shaped articles. The process is characterized by impregnating a plurality of continuous lengths of reinforcing fiber strands with a first thermoplastic resin material while continuously drawing the fiber strands to produce a long fiber reinforcing composite structure followed by coating a second thermoplastic resin material containing additives onto the long fiber reinforcing composite structure to produce a coated, long fiber reinforcing composite structure. The coating additives may be selected from mineral reinforcing agents, lubricants, flame retardants, blowing agents, foaming agents, ultraviolet light resistant agents, heat sensitive pigments, etc. The coated, long fiber reinforcing composite structure prepared according to the process is suitable for the preparation of shaped articles exhibiting good physical and chemical properties.
