Abstract

An impact attenuation system comprises an aluminum honeycomb sheet having a top surface and a bottom surface. The aluminum honeycomb sheet defines a plurality of approximately hexagonally shaped cells. The bottom surface defines a single sheet of contiguous cells and the top surface defines two or more islands of contiguous cells separated by one or more slits. At least a portion of one or both of the top surface and bottom surface may be covered by a polymer skin. The polymer skin may comprise carbon fibers and/or fiberglass.
