ABSTRACT:
A composite tubular member having an outer cylindrical member containing fibers oriented to resist internal pressure while providing low bending stiffness, an inner smaller centrally located core member located near the neutral axis of composite tubular member containing fibers oriented to provide high axial stiffness, high tensile stremgth and low bending stiffness and web members containing fibers oriented to resist shear stress, connecting the outer cylindrical member and the inner core member to form at least two separate cells within the composite tubular member.
