An air inlet deflector for a structure having an air inlet. The deflector may be retractable within the structure, may be integrally formed with the structure, and may prevent the structure from ingesting foreign matter, such as birds. The deflector may include a series of ribs, spokes, or vanes that may vary in width and/or thickness from fore to aft, and/or may be curvilinear in one or more planes of view, and/or may serve double duty as inlet vanes for redirecting inlet air.

1. An aircraft component comprising a fiber-reinforced composite material and further comprising a fore end region and an aft end region relative to an intended direction of an airstream or airborne matter impacted by the aircraft component, the fore end region presenting a first angle of incidence
1. An aircraft component comprising a fiber-reinforced composite material and further comprising a fore end region and an aft end region relative to an intended direction of an airstream or airborne matter impacted by the aircraft component, the fore end region presenting a first angle of incidence and the aft end region presenting a second angle of incidence, the first angle of incidence being more direct relative to the intended direction than the second angle of incidence, the fore end region comprising a first fiber-reinforced material comprising a first impact strength, and the aft end region comprising a second fiber-reinforced material comprising a second impact strength, wherein the first impact strength is greater than the second impact strength, and wherein the fore end region comprises a greater thickness than the aft end region. 2. The aircraft component of claim 1 wherein the first angle of incidence is greater than the second angle of incidence. 3. The aircraft component of claim 1 comprising a varying impact strength portion between the fore end region and the aft end region. 4. The aircraft component of claim 3 wherein the varying impact strength portion comprises impact strengths that vary continuously from the fore end region to the aft end region. 5. The aircraft component of claim 3 wherein the varying impact strength portion comprises impact strengths that vary among different zones between the fore end region and the aft end region. 6. The aircraft component of claim 5 wherein each of the different zones has a different, substantially uniform impact strength. 7. The aircraft component of claim 1 wherein the aircraft component comprises at least a portion of an air inlet deflector, a nose cone, a wing, a tail section, an engine nacelle, an air inlet cowl, a windshield, or a fuselage. 8. The aircraft component of claim 7 wherein the fiber-reinforced composite material further comprises carbon, Kevlar, Twaron, aluminum, or glass fibers. 9. The aircraft component of claim 1 wherein the fiber-reinforced composite material comprises a plastic, a polymer, or a thermoplastic. 10. The aircraft component of claim 1 wherein the fiber-reinforced composite material comprises epoxy, polyester, vinyl ester, or nylon. 11. The aircraft component of claim 1 wherein the aircraft component comprises a molded unitary piece. 12. The aircraft component of claim 11 wherein the aircraft component comprises an injection molded unitary piece. 13. A method of fabricating an aircraft component comprising a unitary piece comprising a fore end region and an aft end region, wherein the fore end region comprises a greater thickness than the aft end region, and wherein the aft end region presents a first angle of incidence and the aft end region presents a second angle of incidence, the method comprising molding the fore end region from a first fiber-reinforced material comprising a first impact strength and molding the aft end region from a second composite material having a second impact strength, wherein the first impact strength is greater than the second impact strength. 14. The method of claim 13 wherein molding the fore end region and the aft end region comprises injecting the first fiber-reinforced material through a first injection port in an injection mold, and injecting the second fiber-reinforced material through a second injection port in the injection mold. 15. The method of claim 13 wherein the molding further comprises molding a transition region between the fore end region and the aft end region, the transition region comprising a blend of the first fiber-reinforced material and the second fiber-reinforced material. 16. An aircraft component comprising a molded unitary piece comprising a fiber-reinforced composite material and further comprising a fore end and an aft end, the fore end presenting a first angle of incidence relative to a direction of an airstream or airborne matter impacted by the aircraft component, and the aft end presenting a second angle of incidence relative to the direction of an airstream or airborne matter impacted by the aircraft component, the first angle of incidence being more direct than the second angle of incidence, the fore end comprising a first fiber-reinforced material comprising a first impact strength, and the aft end comprising a second fiber-reinforced material comprising a second impact strength, the first impact strength being greater than the second impact strength, and the fore end comprising a greater thickness than the aft end. 17. The aircraft component of claim 16 wherein the aircraft component comprises at least a portion of air inlet deflector, a nose cone, a wing, a tail section, an engine nacelle, an air inlet cowl, a windshield, or a fuselage. 18. The aircraft component of claim 16 wherein the fiber-reinforced composite material comprises a plastic, a polymer, or a thermoplastic. 19. The aircraft component of claim 18 wherein the fiber-reinforced composite material further comprises carbon, Kevlar, Twaron, aluminum, or glass fibers.
