Abstract

A reversible energy absorbing assembly including a cellular lattice comprising a shape memory material disposed within an expandable interior region of the assembly, wherein the shape memory material is adapted to expand from a first configuration to an expanded configuration in response to fluid communication with a fluid source. Once expanded, the assembly effectively absorbs kinetic energy of an object upon impact with the assembly. The shape memory material can be thermally activated to restore the first configuration of the energy absorbing assembly. Methods of operating the energy absorbing assembly are also disclosed.
