A team of researchers working at Rice University in the U.S. has demonstrated that graphene is better able to withstand the impact of a bullet than either steel or Kevlar. In their paper published in the journal Science, the team describes how they set up a miniature firing range in their laboratory and used it to test the strength of graphene sheets.

Scientists know that graphene sheets are tough, due to their dense one atom think structure. Until now, however, no one has tested the material for use as armor—to protect against being struck by a speeding bullet. In this new effort, the researchers did just that, albeit at a much smaller scale.
