Abstract
A method of forming a plastic component. The method includes a first step of forming a profile by pulling fibrous material, having been wetted out by a resin, through a first die and curing the composite formed so that it maintains its ultimate shape. The surfaces to be coated are treated to create free radicals (bonding sites) which are then available for bonding of an acrylic compound coating. Thereafter, the acrylic compound is applied to the profile to form a coating directly thereon. Application is effected by passing the cured and treated profile through a crosshead extrusion die. The acrylic compound coating is bonded directly to the profile. The invention also includes a fiber reinforced plastic component manufactured in accordance with the method.
