In response to a request from the Office, Chief of Ordinance, tests were conducted at this arsenal on several samples of K Panels laminates of R- 301-W aluminum alloy with fiberglas submitted by the U. S. Rubber Company collaborating with the Reynolds Metals Company. The resistance of these samples to perforation by cal. .45 steel-jacketed ball projectiles and by the cal. .22 fragment-stimulating projectile, G-2, was so greatly inferior to that of Hadfield manganese steel of equivalent weight-per-unit area that tests with other fragment-stimulators were not conducted. It was noticed that when the overall weight was kept constant but the weight of the aluminum component was increased the resistance of a sample decreased.
