Abstract: A method is disclosed for forming a hollow tube, wherein the tube has a structural layer and a shield layer. The shield layer forms an inner surface of the tube. In some embodiments of the method, a coating, which forms the shield layer, is applied to a wash-out mandrel. The coating typically comprises a metal and/or a ceramic. A composite material, which in some embodiments is filamentous, is applied to (e.g., wound around, etc.) the coating to form the structural layer. In some embodiments, an optional transitional layer is applied to the coating before applying the composite material to enhance their compatibility. The various layers are cured, and then the mandrel is washed away to create the hollow or bore of the tube.
