A hood assembly of a vehicle includes a hood outer panel defining an outer surface of the hood assembly and a hood inner panel defining an inner surface of the hood assembly such that a hood cavity is defined between the hood inner panel and the hood outer panel. An energy absorbing material is located at the hood inner panel. The energy absorbing material includes a multi-cell structure formed of a plurality of interconnected cells having a lattice structure. Each of the plurality of interconnect cells includes at least four nodes and at least one lattice element extending between each of the at least four nodes. The at least one lattice element has a diameter not greater than 2.5 mm.
车辆的发动机罩组件包括限定发动机罩组件的外表面的发动机罩外面板和限定发动机罩组件的内表面的发动机罩内面板,使得发动机罩腔限定在发动机罩内面板和发动机罩外面板之间。能量吸收材料位于发动机罩内面板处。能量吸收材料包括具有晶格结构的由多个互连单元形成的多单元结构。所述多个互连单元中的每一个包括至少四个节点和在所述至少四个节点中的每一个之间延伸的至少一个晶格元件。所述至少一个晶格元件具有不大于2.5mm的直径。
