Table 3 Comparison of results for steel plate (SUS304 and SS400) and aramid fabric
| Material | Condition preventing impact energy of 9 kJ for ballistic ejecta | Mass per unit area (kg/m2) |
|---|---|---|
| SUS304 | Thickness of 1.5 mm (Ep≒11 kJ) | 11.85 |
| SS400 | Thickness of 3.2 mm (Ep≒14 kJ) | 24.96 |
