Utilization of Technology of Explosive Welding at Development of Multilayer Ballistic Resistant Materials


Article Preview

The technology of explosive welding (EXW) was used for development of metallic multilayer ballistic resistant materials. Explosive cladded two or multilayer materials serve as final product or as semi-finished product for further processing, e.g. rolling. The objective is to create material with sufficient ballistic resistance at relatively small thickness of the resulting multilayer structure. Under retaining the weight of armoured vehicle its ballistic resistance can be increased or, under retaining its existing ballistic resistance the weight can be reduced. Resulting material should be producible of commercially available metallic materials using common technologies, especially the technology of roll welding (ROW). For the primary tests it is possible to model the resulting structure by means of EXW and some its properties can be verified in the initial stage of research of the multilayer structure (e.g. tests of heat processing, verification of diffusion processes, behaviour under various types of load, verification of ballistic resistance and other technological tests). Subsequently, production can start of large semi-finished products by means of ROW technology. Effective preparation is possible of the samples of multilayer materials by means of EXW technology in various material combinations - armour steel, tool steel and interlayer based on nickel, nickel alloys etc.
