A stator vane assembly for a compressor (10) has a support structure (14) which carries and is bounded by an annular stator vane structure (11). The stator vane structure (11) comprises a central bore (50) and a sleeve (52,80) carried on the central bore (50). The sleeve (52,80) is disposed between the support structure (14) and bore (50) of the annular stator vane structure (11). The annular stator vane structure (11) is made from a non-metallic composite material and the sleeve (52,80) is made from a first material. The coefficient of thermal expansion of the non metallic material is equal to or less than the co-efficient of thermal expansion of the first material. |
