  • Structures for absorbing impact energy
    Patent number: 4007917
    Abstract: Disclosed is a concept for covering rigid members with a layer of an energy absorbing material, such as a ceramic foam or glass foam. In a specific application of the invention, the foam layer is used to cover highway structures, such as bridge columns. The objective is to make the highway structure capable of absorbing impact energy from a moving vehicle in the event of a collision.
