Graphene stronger than kevlar when blasted with Mach 9 microbullets
This is one other new use for graphene (that may in all probability by no means occur): stopping bullets. College of Massachusetts-Amhers researchers have discovered that everyone’s favourite potential marvel-materials vastly outperforms metal and even kevlar armor. Testing the extremely-light-weight, 1-atom thick carbon sheets has proved tough up to now, as they disintegrated on contact with common bullets. So, the staff used laser pulses to fireside micron-sized glass bullets into the sheets at round 6,seven hundred mph, a few third the velocity of an M16 bullet (see under). Sheets from 30 to 300 layers thick absorbed the impacts a lot better than the opposite supplies by deforming right into a cone form, then cracking.
However — and there is all the time a however with graphene — such sheets are presently too brittle to make right into a strong materials. The reply could be to sew graphene flakes collectively, then range the orientation to stop cracking. No matter, please simply tell us us if you truly flip this materials right into a rattling product.
