In the experiment, scientists at the Rice University in the united states fired microbullets in supersonic speeds in graphene and found which it was better capable to withstand the impact of the bullet than either steel or Kevlar.
Graphene sheets are considered to be tough, with a new dense structure, but had in no way been tested for use as armour as yet.
The researchers setup a miniature firing range within their laboratory and utilised a laser to vapourise gold filaments to serve as gun powder. Micron-sized glass bullets were fired in the graphene targets at speeds as high as 10, 780 km/hour (about one 3rd the speed of the real bullet).
The sheets had the ability to dissipate the energy from the bullet by stretching and also forming tiny cracks to absorb this energy.
Analysis found which the graphene sheets performed twice along with Kevlar, currently utilized in bullet-proof vests, and up to 10 times better than steel.
If it may be produced in enough quantity and in a low price, graphene could form a much better bullet-proof vest, the final results found.
The results of this study were published inside the journal Science.
