Claim 15:
16. A method of manufacturing an airfoil assembly, the airfoil assembly defining a span axis, a root end, and a tip end, the method comprising:
laying up a reinforcement structure comprising a first helical support structure fully wrapped around the span axis between the root end and the tip end and a second helical support structure fully wrapped around the span axis between the root end and the tip end, wherein the first helical support structure wraps clockwise around the span axis and the second helical support structure wraps counterclockwise around the span axis;
applying a polymeric matrix material at least partially around the reinforcement structure; and
positioning an outer skin around the reinforcement structure and the polymeric matrix material to form the airfoil assembly.
