These cracks are somewhat problematic, but they could be easily solved with a composite structure (a ceramic plate, perhaps), or just by using more graphene. Īn illustration of graphene deforming, as it’s struck by a bulletĪs expected, the impact of the bullets caused the graphene to deform into a cone shape - and then cracking radially. As the tiny (micrometer-sized) bullets slammed into the graphene armor, it showed around twice the stopping power of Kevlar, or about 10 times the stopping power of steel plate. They focused a laser on a gold filament, vaporizing it into a projectile bullet that traveled at 3,000 meters per second - or more than twice the muzzle velocity of a high-powered rifle. The researchers tested between 10 and 100 layers of graphene - between 10 nanometers and 100 nanometers thick, respectively.

Usually, a lot of graphene research is simulated or theoretical or extrapolated. This new research, carried out by Rice University and the University of Massachusetts, is notable for being one of first examples of actually testing graphene out. Turns out, it’s super-strong, along with being mega-conductive among other things. This is what perfect graphene looks like: A monolayer of carbon atoms.
