Abstract : Adhesively bonded honeycomb panels commonly used with high performance aircraft were subjected to ballistic impact from a military .30 caliber round to analyze target response qualitatively. Structural panels were impacted by a 150-grain projectile traveling at about 300 ft/sec at angles of 15, 45, and 90 degrees. Experimental data on projectile behavior, projectile impact and exit velocities, and damage sustained by the panels were analyzed. The 15-degree impact angle provided the most extensive damage; the projectile, which completely penetrated the panel, produced a high velocity spall fragment, and the honeycomb structure was delaminated.
