| Abstract | ||
| Concrete is one of the common materials in strategic structures, and because of it, fabric concrete (CC), which is also called fabric reinforced concrete (TCR), is considered one of the latest technologies in the world. According to the general applications of fabric concrete, the need to investigate and evaluate it in the field of military and defense becomes clear, and for this purpose, in this research, fabric concrete targets with dimensions of 120 mm x 120 mm and thickness of 10 mm are subjected to the penetration of steel projectiles with flat, hemispherical and conical noses. have been tested and the velocity of the ballistic limit of a specific fabric concrete sample and the maximum diameter of destruction of the front and back surfaces of the sample have been measured. The failure mechanism of fabric concrete samples has emerged in the form of brittle and fragmentation type failure, which have shown a relatively good performance against the penetration of projectiles, so that the area and diameter of destruction on the front surface of the samples was very small and sometimes as much as the diameter of the projectile. On the back surface of the samples, the amount of destruction is also acceptable and with the increase of the impact speed, the amount of destruction has also increased linearly, and the ballistic limit speed for steel projectiles with flat, hemispherical and cone noses is 124, 110 and 100 m/s, respectively. It is stated that it indicates the easy penetration of projectiles with a conical nose and the difficult penetration of projectiles with a flat nose. | ||
