Polymer-metal composite stator vanes and methods for manufacturing the same

A stator vane, comprising:

• a body configured to be installed in a bypass of a gas turbine engine such that the body impinges a gas flow within the gas turbine engine during operation thereof, the body having a suction side wall configured to face away from the incoming gas flow and an oppositely disposed pressure side wall configured to face towards the incoming gas flow, the body including a polymeric substrate formed of a polymer material and a metallic sheet formed of a metallic material, wherein the metallic sheet covers a portion of the polymeric substrate and is at least partially embedded in the polymeric substrate, wherein the polymeric substrate is formed by an injection molding process, wherein the metallic sheet defines at least part of but not an entirety of the pressure side wall or the suction side wall, wherein the metallic sheet includes a leading portion that covers the polymeric substrate adjacent to a leading edge of the body, an outer portion adjacent to a radially outermost edge of the body, and an inner portion adjacent to a radially innermost edge of the body, wherein the outer portion and/or the inner portion extend further from the leading edge toward a trailing edge of the body than the leading portion, wherein a central region of the body between the leading portion, outer portion, and the inner portion of the metallic sheet is defined by exposed portions of the polymeric substrate.
