The aim of this paper is to investigate the ballistic properties of laminates made of light alloys under various configuration and thickness. The laminates were obtained by explosive welding method. Composite components are aluminum alloy AA2519 and titanium alloy Ti6Al4V with the aluminum alloy AA1050 as intermediate layer. The paper describes the influence of the bullet impact energy on the structure of the panel, depending on the configuration of the laminates: thickness of the layers and the applicated heat treatment. Ballistic resistance tests were carried out in accordance with the standards STANAG 4569 Level 2. The results of the research were compared to the ballistic resistance of typical material used for ballistic shields production.
