Abstract

An energy absorber is provided. The energy absorber includes a thin panel (78) formed of composite materials (84) for reacting compression forces in the plane of the panel (78) between two opposed edges thereof. The panel (78) is constructed to resist overall bending failure when force is applied to the opposite edges. The energy absorber further includes force receiving structure (90, 92) for receiving forces directly to one of the edges and for receiving forces to the opposite edge of the panel (78) to initiate local folding parallel to the other edge for progressing crushing and local folding of the panel (78).
