ABSTRACT:
This invention is directed to a continuous process for producing a molded thermoplastic fiber reinforced article having a high resin concentration in at least one surface thereof. The finished article may be prepared by compression molding and can have a Class A surface. The continuous process includes coating at least one surface of a heated fiber mat core with a melted first thermoplastic resin, passing the fiber mat core into an extrusion zone wherein a melted second thermoplastic resin is extruded onto at least one surface of the fiber mat core and then molding the fiber mat core and thermoplastic resin into a finished article. The continuous process of this invention provides for fast production of molded finished articles such as roof tile, automobile exterior panels, house siding, etc.
