The Development of a Hybrid Thermoplastic Ballistic Material With Application to Helmets

摘要: US helmet material technology has changed relatively little since the introduction of aramids in the 1970s. All US Army ballistic helmets use woven aramids with a thermoset toughened phenolic resin system. The current research explores the use of thermoplastic polyolefin-based matrix material. Although thermoplastic aramid systems have been evaluated for specialty applications, they have often failed to meet all the stringent criteria required of a US Army helmet system. The present work seeks to remedy this by investigating hybrid ballistic …
