ABSTRACT:
A crash attenuator (10) includes a plurality of layers (22) of fibrous cellular material. Each of the layers is comprised of a plurality of hexagonal elongate cells fabricated of a fibrous cellulose material that has a longitudinal axis that is disposed horizontal to the ground such that the edge of the cell is directed toward the impacting vehicle. A flat sheet of fibrous material (24) is disposed between each of the layers to provide an energy dispersing surface. A rear impact plate (18) is disposed on the impacting end of the crash attenuator (10) and is fabricated from a soft metal. A front mounting plate (20) is disposed on the opposite end thereof and the two secured by tension cables (42). The exterior of the layers (22) is covered by sheets (26) and (46). Thereafter, a layer of moisture proof material (78) is disposed over the surface of the crash attenuator (10) to prevent moisture from entering the interior.
