New 3D-printed plastic cubes, developed by a team of scientists of the Los Alamos National Laboratory, could be the used in the next generation of lightweight, explosive-proof armor.
These cubes are printed with fractal voids in them, resulting in better dissipation of shock waves than already available materials. They were tested with an impactor fired at 670 miles per hour. The advantage of this material over others is that the shock wave upon impact can be controlled.
Although the result are very encouraging, the researchers are still open to other options for the design of this material. If successful, this new material could be used in structures, vehicles, and human protection.
