Flex-Core

Aluminum Flex-Core® honeycomb utilizes either 5052 or 5056 alloy foil material and is available in two cell sizes. FlexCore® has unique cell configurations that significantly reduce anticlastic behavior and permit small radii of curvature without deformation of the cell walls or loss of mechanical properties. Aluminum Flex-Core® has been developed to allow the designer and fabricator freedom in the utilization of honeycomb for components requiring simple and compound curvatures. Highly contoured sandwich panels such as leading edges and flaps, nacelles, fairings, doors, and access covers, and other parabolic, spherical, and cylindrical shapes are prime Flex-Core® candidates. Duplicate die model and control tooling for aerospace use are also examples of Flex-Core® Applicationss. As with standard aluminum honeycomb, Flex-Core® provides controlled crush characteristics without rebound and thus curved energy absorption units become feasible and economical.
