Research of Prospective Materials for Military Protective Structures

Abstract

Different types of composite materials with potential application in ballistic protection of static objects are discussed and compared in present study. The studied solutions include: 1) the concretes with or without reinforcement, 2) the metallic boxes with internal gap filled with different materials and 3) the ceramics-metallic composite armours. Besides the ballistic resistance, the areal weight and the price are taken into account. The weight of solutions is important in case of static objects mainly from logistic point of view. The proposals of ballistic compositions presented in the study can facilitate the choice of solutions according to specific requests.

On Diagnostics of Military Fortification Constructions

“…The same situation happens once again in relation to expeditionary style of military operations that can be conducted around the world. This style of operations entailed the requirement for effective temporary structures and installations including field fortifications along with taken advantage of new materials as High Performance Concretes (HPC), Ultra-High-Performance Concrete (UHPC) [5] or High-Performance Fibre Reinforcement Concrete (HPFRC) and others.…”

“…To meet major part of the requirements is task for materials research [5], logistics, tactics as well as engineers. On the contrary, reusability and verification of protective characteristics, especially after exposure to hit or blast posed a problem.…”

“…On the contrary, reusability and verification of protective characteristics, especially after exposure to hit or blast posed a problem. Structures that have been hit by the blast effects (pressure wave, projectile or fragments) should be assessed for their further use [5,7,8,9]. It is therefore necessary to assess whether the fortification structure is capable of withstanding additional actions, or it has already lost its protective function and it can no longer be used for forces protection.…”
