Zusammenfassung:The invention relates to a sacrificial composite part (1, 10, 100) that absorbs the energy released at the time of a vehicle collision with an impacting object (2), said part consisting of an assembly of a plurality of cells (3, 30, 300), each cell comprising a wall (5, 50, 500) connecting a first end (6, 60, 600) and a second end (7, 70, 700) of said cell, the direction of penetration (8) of the impacting object into said part going from said first end to said second end. Said sacrificial composite part of the invention is characterized in that that peripheral wall of each cell has a decreasing thickness (e) from said first end towards said second end of said cell, in the direction of penetration of the impacting object.
