Abstract
A composite tube made from a combination fiber and epoxy is disclosed. The tube may be made by filament winding although other materials and processes are suitable. In one example, the tube laminate is a mix of axial and helical fibers tailored to meet the stiffness and strength requirements of the particular application. Fibers having a different modulus may also be mixed to meet axial and torsional stiffness requirements. For example, high modulus fibers may be used in a helical pattern to handle high torque loads while lower modulus fibers may be used for the remaining portion of the tube laminate. The composite tube may be used for load and/or torque bearing applications and can include a support tube pressed fit into an end of the tube.
