ABSTRACT:
A composite beam having a constant stress geometry is provided wherein a varying fiber content in a fiber impregnated resin is employed across the beam's cross section to cause the neutral axis of the beam to shift toward the compressive side. The design provides the maximum deflection in the direction of the load before compressive failure occurs for a given size and shaped beam of equivalent stiffness.
