Stronger Than Steel, Able to Stop a Speeding Bullet—It’s Super Wood!
Simple processes can make wood tough, impact-resistant—or even transparent
A five-layer, plywood-like sandwich of densified wood stopped simulated bullets fired into the material—a result Hu and his colleagues suggest could lead to low-cost armor. The material does not protect quite as well as a Kevlar sheet of the same thickness—but it only costs about 5 percent as much, he notes.
