In this study, Taylor impact tests of polymer cylinder and metal sleeved polymer core projectiles were performed to investigate the lateral deformation behavior of sleeve during Taylor impact. In addition, high-speed photographs obtained during Taylor impact tests were used for the measurements of the instantaneous local strain, which made it possible to investigate the deformation behaviors of polymeric materials through experiments at high strain rates. And this experimental results were compared with the numerical simulation using an AUTODYN 2D S/W to observe interaction between sleeve and core. Core materials adopted and impact velocity affected the bulging behavior of sleeve projectile. In the case of SUS304 sleeved polymer projectile impact, when the impact velocity was over 220 m/s, the influence of core materials existed; rubber core materials produced a significant bulging of sleeved projectile.
