Ultra-high-strength metamaterial developed using graphene

Ultra-high-strength metamaterial developed using graphene: To maximize the increase in strength imparted by the addition of graphene, the KAIST research team created a layered structure of metal and graphene. Using CVD (Chemical Vapor Deposition) the team grew a single layer of graphene on a metal deposited substrate then deposited another metal layer and repeated the process to produce a metal-graphene multilayer composite material that, achieving a world first in doing so, utilized single layer of graphene...

...Professor Han, who led the research effort, commented "the result is astounding as 0.00004% in weight of graphene increased the strength of the materials by hundreds of times" and that "improvements based on this success, especially enabling mass production with roll-to-roll process or metal sintering process, in the production of automobile and spacecraft lightweight, ultra-high strength parts may become possible."
