Fracture-Resistant 'Rebar Graphene'
Graphene is a one-atom-thick sheet of carbon. On the two-dimensional scale, the material is stronger than steel, but because graphene is so thin, it is still subject to ripping and tearing. Rice University researchers have found that fracture-resistant “rebar graphene” is more than twice as tough as pristine graphene. These simulations show how carbon nanotubes act as reinforcement bars, like steel in concrete. Researchers at Brown University worked with Rice University to show how rebar helps bridge or redirect cracks in graphene under strain.
