The resistance of single sheets of this material was so low as to be indeterminable by the test methods employed. The resistance of six plies of this material to perforation by caliber .45 ball projectiles steel-jacketed was about equal to that of solid pieces of aluminum alloy previously tested, whereas the resistance to perforation by the 17 grain fragment-simulator, G-2, or a similar combination was somewhat superior to that of solid pieces of equivalent weight. The resistance sof the subject material is low as to eliminate it from consideration as a potential body armor material.
