EXPERIMENTAL INVESTIGATION FOR THE BEHAVIOR OF MULTI–LAYERED TARGET UNDER PROJECTILE IMPACT

This paper presents the ballistic performance of transparent polymer materials. The need to design transparent projectile protective armour leads to research on ballistic limit for the type of material. The ballistic resistance of different type of layered sandwich polymer/plates was investigated polycarbonate and Polymethylmethacrylate materials were chosen as test cases. The materials were subjected to an impact against a rigid spherical steel projectile in the range of 100 – 650 m/s up impact velocity. The relationship between the initial and final velocity was correlated and validated against existing literature. A very good agreement between the experimental result and Ipson and Recht was presented. The propose empirical equation between initial velocity and final velocity is obtained from statistical analysis
