This article discusses the issues related to the planning of activities for ensuring the physical security of critical infrastructure sites. The critical infrastructure is considered as an important element of the national security of the country, and the cri ticality is determined by the interdependence between the individual elements and the dependence of the society on its normal functioning.

Compression was carried out of modified copper powder workpieces at a pre-determined value of the pressure. High temperature sintering of the workpieces in a neutral medium at a temperature of 1,000°C was performed. A high density metal-ceramic composite material was obtained. Its structure and physico-chemical parameters were determined. Lead-free prototypes were created, corresponding to the weight and dimensions of the reference standard lead passive elements for high energy impact.
