Crashbox type tubular beam e.g. bumper beam, for vehicle, has tubular body with inner reinforcement made of natural or synthetic material with oriented cellular structure, where cellular axis is perpendicular to longitudinal axis of beam
The beam has a tubular body (1) with an inner reinforcement (3) over its entire or part of the length, where the reinforcement is made of a natural or synthetic material with oriented cellular structure. A cellular axis is perpendicular to a longitudinal axis (2) of the beam. The cellular material can be made of balsa wood and the tubular body can be made of magnesium or aluminum alloy section or sheets.
