Influence of ceramic properties on the ballistic ...
In the case of ceramic plates based on Al 2 O 3 also obtained the greatest value of ballistic efficiency ∆ec for samples containing ceramics with a thickness of 4.5 mm. Al 2 O 3 ceramic plates with a thickness of 9 mm also had a low acoustic impedance (42.28 ± 6.75 Mray) in comparison with ceramic plates with a thickness of 4.5 mm (41.5 ± 5 ...
