Graphene has exhibited better qualities as a bullet proof material in comparison to Kevlar or steel in an experiment carried out by researchers at Rice University and the University of Massachusetts. According to a research paper published in journal Science, graphene is twice better compared to Kevlar. The research team found graphene with amazing qualities as it is highly flexible and light. Only issue with graphene is brittleness of its sheets.
While carrying out small-scale ballistics tests, University of Massachusetts Department of Mechanical and Industrial Engineering researcher Jae-Hwang Lee and his team found that graphene has better impact absorbing qualities. Graphene is thinner, flexible and strong material made from single atom sheets arranged in honeycomb structure.
Researchers concluded that graphene could be used as an important material for life saving bulletproof vests after overcoming certain limitations.
Scientists at Rice University fired micro-bullets at graphene sheet at supersonic speed. The experiment is first of its kind to check strength of graphene as armour and security material. Graphene was found to have ten times better impact absorption ability compared to steel.
The micron-sized glass bullets were fired at a speed of 6,700 mph. However, the impact hole was larger in size in graphene sheet. BBC News online science editor Paul Rincon said, “Observations using an electron microscope revealed that graphene dissipates energy by stretching into a cone shape and then cracking in various directions.”
The impact of micro-bullets on graphene was on a wider area, similar to the impact on trampoline when someone jumps. Graphene was found two times better in comparison to Kevlar and 10 times better than steel.
Graphene has been termed as game-changer for the electronics industry. Use of graphene could change the electronic circuits and equipments in various categories of products in near future. Many companies and universities are carrying out extensive research on commercial production and use of graphene in electronics.
