New origami-inspired shield deflects handgun bullets

New origami-inspired shield deflects handgun bullets

"We worked with a federal special agent to understand what their needs were, as well as SWAT teams, police officers and law enforcement, and found that the current solutions are often too heavy and not as portable as they would like", said Larry Howell, Professor at Brigham Young University.

When expanded, which only takes five seconds, the bulletproof shield can offer cover for police officers and shield them from bullets such as the 9 mm, .44 Magnum and.357 Magnum. The shield is made from 12 layers of bulletproof Kevlar with an aluminum core in the middle, and was designed using a common origami creasing pattern, so that it folds into a more manageable size.

"What we really like about this shape is that is has this curvature so that it goes all the way around the person, not just the front, and that's something that traditional barriers have, or shields-they're just kind of flat", Bateman said.

Engineers from Brigham Young University (BYU) have developed a foldable bulletproof kevlar shield that can be quickly set up in an emergency to protect law enforcement operatives from gunfire. "Then you can easily fold it up and move it if you need to advance your position".

In a Secret Montana Cabin, Tom Brady Says He Feels No Pain
The Patriots ran 93 offensive plays and rolled up 546 yards with 37 first downs against the Atlanta defense. Brady finished with 466 yards passing and two touchdowns, hitting on passes to seven different receivers.

This new shield is also lightweight, weighing only 55 pounds. The shield proved surprisingly durable during tests.

Now still in prototype form, the team is continuing to work with law enforcement agencies and has tested it with officers on site who have been impressed. "We suspected that something as large as a.44 Magnum would actually tip it over, but that didn't happen".

The prototypes were constructed to be protective and stiff, while maintaining the flexibility of Kevlar fabric.

The ancient art of origami has been inspiring engineers and designers for decades. The radiator deflates or expands according to the temperature of the satellite.
