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.

Abstract: In an alpine ski there is provided a simplified laminated construction by providing a glass fiber reinforced beam laminated on the tensile facing to a single laminate layer of stiffening material and a bottom running surface. Grooves are machined into the central glass fiber reinforced beam to adjustably control both the ski's weight and stiffness and a continuous metallic sidewall is provided between the bottom edges and the top edges. A decorative cap that conforms to the contour of the top surface of the glass fiber beam is laminated to the beam.
