New research, funded by the Army and Navy and published in June, demonstrates that a novel kind of nanomaterial architecture was robust against super-tiny projectiles, which could lead to stronger armor in the future.
A bullet is a metal mass at velocity, designed to tear a hole in a person. Bulletproof armor, from early metal plate to kevlar to more advanced concepts, works by dispersing that energy as quickly and efficiently as possible, ideally leaving the wearer bruised instead of punctured.
For bulletproof armor to be effective, it needs to distribute and deaden the energy of bullets quickly, it needs to be durable against repeat impacts, and it needs to be light and useful enough that people actually wear it.
