Table 2, shown below, provides the results for 0.500 in. ×0.025 in. (12.70 mm×0.635 mm) strips. Multiple tests were run for each respective comparative example (e.g., 1A and 1B represent the results of two distinct tests performed for the aluminum alloy of Comparative Example 1). Armor layers formed from each of the Comparative Examples 1A, 1B, 2A, 2B, 3A, and 3B were found to pass the tension test and bend test. And while portions of armor could be formed from each of Comparative Examples 1A, 1B, 2A, 2B, 3A, and 3B, interlocking armor layers could not be produced consistently and continuously at full speed from any of the formulations. As shown in Table 2, each comparative example experienced multiple breaks during formation of the armor layer, as the armor layers were generally too brittle.

Table 3, as shown below, provides the results for 0.375 in.×0.022 in. (9.53 mm×0.559 mm) strips. Armor layers formed from each of the Comparative Examples 1C, 1D, 2C, 2D, 3C, and 3D were found to pass the bend test. However, none of the armor layers formed from each of Comparative Examples 1C, 1D, 2C, 2D, 3C, and 3D were able to pass the tension test (at 300 lb).
