Abstract: A composite airfoil has a root, a tip, a root region and a tip region. The composite airfoil further includes a woven core, a first filament reinforced airfoil ply, a second filament reinforced airfoil ply and a local reinforcement laminate section. The woven core extends from the root to the tip of the composite airfoil. The first filament reinforced airfoil ply is stacked on the woven core and the second filament reinforced airfoil ply is stacked adjacent to the first filament reinforced airfoil ply on the woven core. The local reinforcement laminate section is at the tip region of the composite airfoil and comprises a first reinforcement ply that does not extend to the root region. The local reinforcement laminate section increases a chordwise flexural stiffness of the tip region.

Abstract: The disclosed composite airfoil includes a three-dimensional composite core extending longitudinally and having a chord-wise direction. The core has a core in-plane thickness extending between opposing sides in a through-plane direction generally perpendicular to the chord-wise and longitudinal directions. A composite skin covers the opposing sides and has an exterior surface providing an airfoil contour. The skin includes a total skin in-plane thickness corresponding to a sum of thicknesses through the skin in the through-plane direction from each of the opposing sides to their adjoining exterior surface. A sum of the core in-plane and total skin in-plane thicknesses at a central portion of the composite airfoil is a total in-plane thickness. The total skin in-plane thickness at the central portion is less than 50% of the total in-plane thickness.
