Abstract

A composite tubular member having an outer cylindrical member containing fibers oriented to resist internal pressure and provide low bending stiffness, and two inner smaller core members located near the neutral axis of the composite tubular members containing fibers oriented to provide high axial stiffness, high tensile strength and low bending stiffness and fibers oriented to resist shear stress, positioned opposite each other and adjacent to the inner walls of the outer cylindrical member.
