A gas turbine engine (10) has a row of fan stator vanes (18) extending radially across a flow path (20) and joined to inner and outer cases (22) and (24). A vibration damping shroud (78) includes a radially extending chamber (84) for receiving one end of each stator vane in a primary vibration damping material (86). At least one pin receiving cavity (88), independent of the chamber, contains a secondary vibration damping material (92) which slidably engages a corresponding support pin (72) extending from the adjacent case (22) to anchor the vane to the case. The independence of the chamber and the cavity enables the use of different primary and secondary materials capable of satisfying conflicting performance requirements.
