Abstract
In order to investigate the characteristics of penatration and the effect of surface treatment in A15052-H34, Al5082-Hl31 and titanium alloy laminates which were treated by anodizing and PVD(Physical Vapor Desposition) method, ballistic tests were conducted. Thickness of surface membrane in A15052-H34, Al5082-Hl31, were $25{\mu}m$ and that of titanium $0.9{\mu}m$ respectively. Surface hardness test was conducted using micro Vicker's hardness tester. Resistance to penetration is determined by the protection ballistic limit(V50), a statistical velocity with $50\%$ probability for complete penetration. Fracture behaviors and ballistic tolerance, described by penetration modes, are observed from the results of V50 test and Projectile Through Plate(PTP) test at velocities greater than protection ballistic limit, respectively. Present experimental results derived from this research help to optimize laminate impact behavior by varing the laminate thickness and surface treated materials.
