The optimization of fiber-reinforced backpanel as a substrate for ceramic/composite ballistic inserts for personal protection [PDF]

open access: yes, 2013
Pure fiber-reinforced polymer composites can give protection only of a certain level of ballistic threat i.e. only of small arms ammunition. For higher ballistic threat of high energy projectiles, ballistic inserts of ceramic tiles/composite back panel ...
