DUAL-HARDNESS TITANIUM BODY ARMOR FOR CONCEALABLE APPLICATIONS
ENS Berl Mclaurin, USN
A current need exists to develop a lightweight low-profile armor system capable of defeating a 7.62x39mm ball round at muzzle velocity. Three design requirements must be met within the development of this system: areal density less than 5lbs/ft2, an overall thickness < 8mm and enable formability to match torso contours. This study will focus on study focuses on pure Ti (Grade 2) and a single Ti alloy Ti6Al-4V (grade5). Both materials exhibit superplastic behavior to enable shaping to the torso. Initial studies will focus on laminate systems of both homogeneous and heterogeneous layered structures to investigate pressure reduction mechanisms. In addition to layered systems, hard front face coatings will be studied as an alternative approach to reducing the penetration pressure through initial blunting of the incident projectile. All test configurations will be investigated both experimentally and through hydrocode modeling.
