متن کاملBallistic Body Armor
P O L Y M E R S Our goal is to prevent the catastrophic failure of ballistic body armor by developing measurements and predictive models to test and determine the long-term reliability of polymers used in ballistic resistant armor. Our approach, which utilizes conventional analytical techniques in addition to newly developed minimally invasive test methods, seeks to identify the chemical and me...
متن کاملLarge-displacement Lightweight Armor
Large-displacement Lightweight Armor Randomly entangled fibers forming loosely bound nonwoven structures are evaluated for use in lightweight armor applications. These materials sacrifice volumetric efficiency in order to realize a reduction in mass versus traditional armor materials, while maintaining equivalent ballistic performance. The primary material characterized, polyester fiberfill, is...
