An experimental study of the high velocity impact on 2/1 GLARE panels has been carried out. Four GLARE 3 panels with (Al/0/90/Al), (Al/02/902/Al), (Al/04/904/Al) and (Al/08/908/Al) configurations were fabricated. All panels had same aluminum thickness. Ballistic tests were conducted using flat ended steel projectiles. The failure processes and energy absorption mechanisms were characterized by observation the front and rear sides and also sectioning the panels. Some global and local failure modes due to high velocity impact were identified. The ballistic limit velocity of each panel set was determined experimentally. It was found that the (Al/02/902/Al) sequence has the superior specific perforation energy.
