A duct section and sys-tem, including a laminated shroud, act-ing as a secondary duct, for aerospace and other applications, and a method for constructing same. The duct structure incorporates a metallic primary duct tube, with a laminated shroud surround-ing the primary duct tube and separated therefrom by an annular gap. The lami-nated shroud includes a metallic inner layer and a polymeric outer layer. Preferably, the thin metallic layer is a corrosion resistant material such as cor-rosion resistant stainless steel or titani-um. In one embodiment of the inven-tion, the outer polymeric layer is a poly-imide material, such as polyimide resin--impregnated fiberglass cloth. |
