In order to protect the structural steel sheet from the impact of the blast wave, the steel sheet was covered with a composite material consisting of aramid fabrics with a surface density of 200 g/m2 (3 layers) and 350 g/m2 (3 layers). The total thickness of these layers was 2.4 mm. Turkish produced BRE 450 polyester resin was used to connect the layers. The composite was coated on top with the same resin filled with crumb rubber 1.5 mm in size. The thickness of this coating is 2.2 mm. The protective agent thus ob...

Nowadays, along with creating materials with enhanced mechanical characteristics, it became important in the light of ecological problems, to design eco-friendly materials capable to disappear with time after fulfilling functions, in other words to develop biodegradable mechanically strong materials. The chemistry and technology of biodegradable polymers is one of the most important and rapidly developing fields of modern polymer science. A lot of biodegradibel polymers (BPs) were created mostly for medical applic...
