Abstract
An airfoil vane multiplet includes airfoil tubes that each have airfoil tube fiber plies. A plurality of the airfoil tube fiber plies extend along the airfoil tube and turn to project outwardly from the airfoil tube. Connector fiber plies include airfoil holes through which the airfoil tubes extend. The connector fiber plies are interleaved with the plurality of airfoil tube fiber plies such that the airfoil tubes are secured together.
