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.
L'invention concerne une structure de conduite stratifiée pour des turbines à gaz, et un procédé de fabrication de structures de conduite stratifiée pour des turbines à gaz. La structure de conduite incorpore une couche interne métallique et une couche externe polymère. De préférence, la couche métallique mince est un matériau résistant à la corrosion tel que de l'acier inoxydable ou du titane résistant à la corrosion. La couche polymère externe de support est, dans un mode de réalisation préféré de l'invention, un matériau de poly(imide), tel qu'un tissu en fibre de verre imprégné de résine de poly(imide).
