Experimental and numerical study on ballistic resistance of polyurethane-coated thin HPFRC plate

Popis výsledku v původním jazyce

High-performance fiber-reinforced concrete (HPFRC) can be used to build light bulletproof structures because even its thin layer can prevent projectile perforation. However, when uncoated, the pieces of debris may break off the structure during a projectile impact. The resulting secondary fragments can cause personal injury or damage to property in the structure surrounding. This study shows that coating the thin HPFRC panel with polyurethane (PU) prevents the formation of such fragments on the back and narrows the fragment beam on the front. The experimental program is composed of two parts: the ballistic tests of the uncoated and coated specimen and the additional tests required for determining the mechanical properties of HPFRC and PU. Numerical models created independently of ballistic tests and using only conventionally measured data, satisfactorily predict the ballistic resistance of the panels.
