Abstract
A method of fabricating a composite tubular member includes providing a mandrel having a central longitudinal axis and wrapping a plurality of composite fiber layers around said mandrel wherein the longitudinal axis thereof is oriented at a first angle with respect to the longitudinal axis of said mandrel. The composite tubular member produced does not have any longitudinal seams and is thus considerably stronger and more durable than prior art composite tubes.
