초록

A laminated duct structure for gas turbine engines, and a method for manufacturing laminated duct structures for gas turbine engines. The duct structure incorporates a metallic inner layer and a polymeric outer layer. Preferably, the thin metallic layer is a corrosion resistant material such as corrosion resistant stainless steel or titanium. The supporting outer polymeric layer is, in a preferred embodiment of the invention, a polyimide material, such as polyimide resin-impregnated fiberglass cloth.
