Reinforced hybrid structures and methods thereof

Abstract

The present invention discloses a method for producing an aircraft wing hybrid structure comprising the steps of producing a machined metallic bottom skin by either (i) pre-machining, (ii) preforming or (iii) combinations thereof, finishing the machined metallic bottom skin, providing a finished machined metallic bottom skin that serves as a lay-up mold, placing a plurality of core straps on top of the finished machined metallic bottom skin, arranging a skin that is selected from the group consisting of a monolithic skin, a fiber metal laminate skin and a non-reinforced metallic laminate skin on top of the plurality of cores strap to form a module, and curing the module, wherein the finished machined metallic bottom skin is the load carrying element in the aircraft wing hybrid structure. In another embodiment, the present invention discloses a method for producing an aircraft wing hybrid structure comprising the steps of providing a lay-up mold, placing a first skin that is selected from the group consisting of a monolithic skin, a fiber metal laminate skin and a non-reinforced metallic laminate skin on a lay-up mold, placing a plurality of core straps on top of the skin, arranging a second skin that is selected from the group consisting of a monolithic skin, a fiber metal laminate skin and a non-reinforced metallic laminate skin on top of the plurality of cores strap to form a module, and curing the module.
