In the compressor section of a gas turbine engine, a stator assembly comprises an outer vane support structure, an inner vane support structure, and a plurality of stator vanes which extend radially therebetween. The inner vane support structure includes a one piece inner ring, and a plurality of shroud sections which surround and are bonded to the ring. Each shroud section has arcuate cavities which receive and retain therein the inner end of a stator vane. The ring and shroud sections are fabricated from composite materials.
