Air Force Academy cadet Hayley Weir has been fiddling with ways to combine Kevlar, carbon fibers, and “shear thickening fluid” (all I know about that last one is that it’s goop that hardens when you hit it). She’s come up with a sandwich that apparently is the business when it comes to calming down kinetic energy impacts. And apparently the stuff is also a case of ‘the slow blade penetrates the shield:’
The team tested 9 mm, .40 Smith & Wesson, and then the .44 Magnum rounds.
[USAF Academy Professor] Burke said the stronger and faster the round, the quicker it was stopped by the material.
In the 9 mm testing, the rounds went through most of the layers but were caught by the fiber backing, Burke said. The larger .40-caliber round was contained in the third layer of Kevlar. The .44 Magnum was caught in the first layer.
