Ballistic Performance of Al2O3 and SSiC Ceramic with Areal Density of 26 kg/m2 against 7.62 mm Calibre Projectiles
Popis výsledku v původním jazyce
The present study deals with ballistic performance of corundum and silicon carbide ceramics against 7.62 mm calibre projectile. In particular, ceramic samples of dimension 100 x 100 mm with various thickness in the range of 6.94 – 6.96 mm and 7.77 - 7.79 mm were glued to Al plate with thickness of 8 mm and tested against 7.62 mm calibre projectiles, namely 30.06 M2 AP, 7.62 mm x 51 AP (WC) and 7.62 mm x 54 R B32. The conducted tests have provided the V50 value for tested materials composed of 8 mm Al plate and ceramic. Furthermore, applying linear approximation the value V50 for normalized ceramic areal density of 26 kg/m2 was calculated. From the given V50 values, the energy of projectile absorbed in ceramic and in Al plate was also calculated. Finally, the results showed that corundum ceramic exhibited significantly lower ballistic efficiency probably due to lower thickness (26 kg/m2 corresponds to thickness of 6.61 mm) in comparison with SSiC ceramic (26 kg/m2 corresponds to thickness of 8.33 mm). The highest efficiency showed 7.62 mm x 51 AP (WC) with a hard core against both ceramics. An unexplained point remains similar V50 value for 30.06 M2 AP and 7.62 mm x 54 R B32 projectile for corundum ceramic and significantly different for SSiC ceramic.
