Abstract
A composite shaft comprises a plurality of composite elements arranged about an axis to form a hollow cylindrical shaft extending along the axis between a first end of the shaft and a second end of the shaft. The plurality of composite elements incudes: a first group of the composite elements aligned parallel to the axis, a second group of the composite elements arranged about the axis offset by an angle α relative to the first group in a first direction, a third group of the composite elements arranged about the axis offset by an angle γ relative to the first group in a second direction opposite the first direction, wherein the third group is offset from the second group by an angle 2α, and a fourth group of the composite elements arranged about the axis offset by an angle θ.
