Abstract

An injection molded component having at least one structural layer of material and at least one fuel vapor barrier layer carried by the structural layer, and a method of making it utilizing separately injection molded structural and fuel vapor barrier layers. The vapor barrier layer may be trapped between two other interconnected layers, or may be bonded to a structural layer by an adhesive. In one form, a fuel vapor barrier layer and a structural layer are separately molded onto a preformed adhesive layer. Desirably, the heat generated during the steps of molding both the vapor barrier layer and the structural layer onto the adhesive layer is sufficient to activate the adhesive and bond the layers together. In another form, a fuel vapor barrier layer is bonded to a layer comprised of a blend of structural and adhesive materials. In yet another form, a fuel vapor barrier layer is disposed and captured between two interconnected structural layers.
