ArmorDillo® is a heavy-duty, waterproof textile designed to protect valuable equipment against outdoor elements such as rain, dirt, salt, ultraviolet rays, and damage from other external factors that is manufactured by Transhield® USA and is currently in service with many branches of the United States Armed Forces, primarily the United States NAVY. Due to emerging security threats to classified military hardware the US NAVY through the United States Naval Surface Warfare Center (NSWC) is actively researching and sourcing a textile replacement for ArmorDillo® to meet these threats. This study investigates the mechanical durability of ArmorDillo® under mechanical tearing at 0°, 15°, 30°, 45°, 90° angles respective to the manufactured direction of the fabric under dry conditions for analysis and comparison with intended replacement textiles. Failure analysis was performed by visual and video observations to determine failure cause and assess difference in mechanical performance between textiles and correlate failure to load behavior.
