Preparation of Integrated Ceramic Armor for Body Bulletproof by Semi-Aqueous Gel-Casting

摘要

Arc-shaped integrated alumina ceramic armor for body bulletproof with the size of 300 × 250 × 6 mm,R400mm were prepared by semi-aqueous gel-casting.The excellent characters and advantages of the semi-aqueous gel-casting were analyzed; ballistic experiments were carried out to test the protection coefficient of 92％,96％and 99 alumina ceramics.The experimental results showed that the 92％ alumina ceramic and the 99％ alumina ceramic had favorable performance while the 96％ alumina ceramic had the worst one.But the 92％ alumina ceramic had the highest protection coefficient which is 9.96.
