Resistance of Four Types of Thin Aluminum Alloy Sheet to Perforation by Fragment-Simulating Projectiles

Abstract

In conjunction with a program of development of improved body armor components which is being conducted at this arsenal in response to a request of the Office, Chief of Ordnance, samples of four aluminum alloys have been tested in thin (.125 in.) sheet form. Of the four alloys tested (R-301T, R301W, 14S-W, 24S-RT) the resistance of the 24S-RT sample to perforation by caliber .45 (steel jacketed) ball projectiles and by a light-weight (17 grain) fragment simulator was highest and that of the R-301T sample lowest. However, as compared with that of Hadfield manganese steel of equivalent weight the resistance of all these alloys was remarkably poor.
