Abstract
Disclosed is an energy absorbing bumper formed of curved sections manufactured by pultrusion. The sections have perpendicular borders whose raised edges are connected by closure plates in areas of high stress. The face of the section can be formed with ripples so as to insure that reinforcing wires remain in areas subjected to high stresses.
