Administrator Lite Posted July 9, 2010 Administrator Share Posted July 9, 2010 A liquid armour has been shown to stop bullets in tests carried out by UK scientists at BAE systems in Bristol.The researchers have combined this "shear-thickening" liquid with Kevlar to create a new bullet-proof material.The company is keeping the chemical formula of the liquid a secret, but it works by absorbing the force of the bullet strike and responding to it by becoming much thicker and more sticky.The BAE scientists describe it as "bullet-proof custard"."It's very similar to custard in the sense that the molecules lock together when it's struck," explained Stewart Penny, business development manager in charge of materials development at the company.Shear-thickening liquids are not new to military research. The US Army Research Laboratories has carried out tests using similar liquids.But, according to BAE, these latest tests provide the first clear evidence that liquid armour could effectively protect soldiers from bullets or shrapnel.They say the liquid could ultimately be used to make much lighter, more flexible and more effective bullet-proof vests for solidiers."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.The results were presented to journalists during a preview of future defence technology at BAE's Advanced Technology Centre in Filton, Bristol.

Toshiro Posted July 9, 2010 Share Posted July 9, 2010 Hmm really interresting.. :) "bullet-proof custard"HMMM :lol: Link to comment Share on other sites More sharing options...
myidisbb Posted July 9, 2010 Share Posted July 9, 2010 and how much does that dang system weigh? Link to comment Share on other sites More sharing options...

shought Posted July 12, 2010 Share Posted July 12, 2010 It's definitely woppy:angry:How to prevent the liquid from moving all over the place?It's a fluid between layers of Kevlar. The liquid won't move around a lot because of that alone, but they could even consider a 'chamber-like' structure.|¯¯|¯¯|¯¯|¯¯|ps do note they are still using 10 layers of Kevlar and this all in like 2-5 centimeters, so there's very little room for the liquid to move around (or rather: go to the bottom). They'll just have to fixate the plates and maybe implement this chamber-like structure and then the liquid will stay. Link to comment Share on other sites More sharing options...
