EvoShield is a privately held company located in Athens, Georgia that specializes in performance-driven sports protection with multi-sport applications. “The company, which was founded by athletes makes wrist guards, elbow guards, as well as rib and heart protectors. But unlike the rest of the marketplace, which are sold as a one-size-fits-all product, EvoShield uses a proprietary substance that turns a gel into a hardened material and allows consumers to custom fit their protective device”〔Rovell, Darren."Evoshield Gets Big Buzz before It Hits Stores." CNBC.com. 2010.〕 EvoShield differentiates themselves from competitors through the use of their unique “Gel-to-Shell” technology. Their patented material reacts with elements in the air and turns the product from a soft, moldable material to a hard and durable shell. ==Technology== EvoShield’s protective shields are made of a unique porous composite material that hardens with exposure to air. As the shields harden, they form to the shape of the athlete’s body, creating a custom fit protective guard. The material begins soft and flexible, but the chemical components inside the gel-like pads begin to harden when the shields are removed from the foil bag. In about 20–30 minutes, the once soft pad transforms into a hard and protective guard that is permanently molded to the desired shape. Results from intensive impact deformation testing have shown that EvoShield products disperse the force of impact better than EVA foam and hard plastic, the most common materials found in sports protection. The results, shown below, are measures of backface deformation. Backface deformation is the effect of a non-penetrating projectile on the rear face of a strike plate. It essentially measures how far an object is allowed to protrude against a protective surface. The extent of allowable deformation set by NIJ is 44 mm.” 〔Erwin, Sandra.Army’s Procedures for Testing Body Armor Stir Controversy. NDIA, 2009.〕 The items tested include: EvoShield’s Chest/Rib Guard, a competing Batter’s Chest Guard, a Catcher’s Chest Guard and a bare subject. 〔Southern Impact Research Center, LLC. no R3442.〕 File:EvoShield Impact Chart.png As evidenced by the chart, EvoShield’s Chest & Back Guard generated almost 4 millimeters less of backface deformation than the competing chest protector and almost 10 millimeters less than wearing no protection at all. EvoShield yielded some of the best impact results ever seen for a material of its weight and thickness. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「EvoShield」の詳細全文を読む スポンサード リンク
