Abstract

In an embodiment, an energy absorbing device comprises: a metal component comprising greater than or equal to three walls forming a metal component channel; and a plastic component having a honeycomb structure with a plurality of walls defining comb channels therein. The plastic component is located in the metal component channel forming a crash can. The plastic component is inseparable from the metal component without damage to the metal component and/or the plastic component. In one embodiment, a method of making an energy absorbing device can comprise: co-molding the metal component and the plastic component to form a crash can. The energy absorbing device can be used on a vehicle, adjacent to a vehicle component.
