Abstract

The present application relates to an airfoil (61) for a gas turbine engine (20) including, among other things, an airfoil section (62) extending in a spanwise direction, extending between a leading edge and a trailing edge in a chordwise direction, and extending in a thickness direction between a pressure side and a suction side. The airfoil section (62) has a main body (72) and a first skin (70). The main body (72) includes a plurality of ribs (74) defining a plurality of internal channels (76). The first skin (70) is attached to the main body (72) to enclose the plurality of internal channels (76) such that the main body (72) and the first skin (70) cooperate to define the pressure and suction sides. A damper (82) has at least one layer of damping material sandwiched between the first skin (70) and the plurality of ribs (74). A method of forming a gas turbine engine component (60) is also disclosed.
