A US company has engineered a new type of wood that it says has up to 10 times the strength-to-weight ratio of steel, while also being up to six times lighter. “Superwood” has just launched as a commercial product, manufactured by InventWood, a company co-founded by material scientist Liangbing Hu. Over a decade ago, Hu set out on a quest to reinvent one of the oldest building materials known to humankind. While working at the University of Maryland’s Center for Materials Innovation, Hu, who’s now a professor at Yale, found innovative ways to re-engineer wood. He even made it transparent...

Simple processes can make wood tough, impact-resistant—or even transparent Some varieties of wood, such as oak and maple, are renowned for their strength. But scientists say a simple and inexpensive new process can transform any type of wood into a material stronger than steel, and even some high-tech titanium alloys. Besides taking a star turn in buildings and vehicles, the substance could even be used to make bullet-resistant armor plates. Wood is abundant and relatively low-cost—it literally grows on trees. And although it has been used for millennia to build everything from furniture to homes and larger structures, untreated wood...
