Weaving wool into Kevlar improves the energy and water absorption of the synthetic textile, potentially making bulletproof vests more comfortable and more affordable, according to researchers in Australia.
Tightly woven wool reduces the number of Kevlar layers required to stop a bullet from 36 to 30, and wool’s water-absorption qualities could make Kevlar more effective in wet situations.
Liquid armor has been shown to stop bullets more effectively than plain Kevlar, according to British firm BAE Systems. The material could be used to make thinner, lighter armor for military personnel and police officers, the BBC reports.
Materials scientists combined a shear-thickening liquid with traditional Kevlar to make a bulletproof material that absorbs the force of a bullet strike by becoming thicker and stickier.

As his convoy rode toward Balad, iraq, on a 116-degree day last July, U.S. Army Staff Sergeant Robbie Doughty sat facing out the side of a Humvee, gun in hand, scanning the roadside to head off an ambush. Then: boom, and smoke everywhere. When Doughty looked down, blood was gushing, most of his right leg was gone, and his left leg had taken a dogleg at the shin.
