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.
A good bullet-resistant ride can do the trick for most VIPs, leaving aside physics-defying assassins and impossible curving bullets. But the U.S. Department of Defense also wants controllable protection against the sun's vicious ultraviolet rays, not to mention prying eyes and sniper scopes.
