Fragment penetration of monolithic plate and resin-bonded sheet laminates of aluminum alloy 7475-T371, all of equivalent areal density, is reported as a function of velocity, obliquity, and laminate design. Fragment-simulating projectiles weighing 5.85 and 17.0 grains were used in ballistic tests over ranges of velocity comparable to those attained by actual fragments of 23-mm HEI shell. Findings are discussed with relation to aircraft vulnerability. Author
