Abstract
In this paper, the experimental investigation of impact responses of panels made of a hybrid fiber engineered cementitous composite (ECC) subjected to small hard head steel projectile impact with the impact velocity in the range of 300 m/s and 540 m/s is reported. The hybrid fiber ECC contains 0.58% volume steel fibres and 1.75% volume low modulus polyvinyl-alcohol (PVA) fibres. The constituents of the ECC mix and its material characteristics are introduced briefly in this paper. Impact test results of concrete panels made of conventional concrete are also reported for comparison of the impact resistance capability. The post failure modes of the panels and the damage parameters after impact were analyzed and compared. The test results demonstrate significantly improved impact and shatter resistance of the new hybrid- ECC mix with reduced spalling and fragmentation, localized damage areas, and improved cracking resistance with distributed microcracking.
