Liquid armor has been in the news quite a few times over the past couple of years. It looks like the technology is progressing nicely. BBC News reports …

The BAE scientists describe it as “bullet-proof custard”.

…

“In standard bullet-proof vests, we use thick, heavy, layered plates of Kevlar that restrict movement and contribute to fatigue,” said Mr Penny.

In the tests, scientists used a large gas gun to fire ball bearing-shaped metal bullets at over 300 metres per second into two test materials – 31 layers of untreated kevlar and 10 layers of kevlar combined with the shear-thickening liquid.

“The Kevlar with the liquid works much faster and the impact isn’t anything like as deep,” he explained.
