註釋This paper reviews the results of recent laboratory research studies focusing on the behavior of hybrid fiber Engineered Cementitious Composite (ECC) panels subjected to low- and high-velocity projectile impact. The reviewed laboratory studies include high-velocity (300-700m/s) small-size projectiles impact tests conducted on 0.30×0.17m hybrid fiber ECC prismatic panels of various thicknesses (representing a section of a door or wall), low-velocity large projectile impact tests conducted on both full scale hybrid fiber ECC blast/shelter panels (2.0×1.0×0.05-0.1m), and 1/3 scale hybrid fiber ECC strengthened masonry wall panels (1.0 x 1.0 x 0.1m). Recent results obtained from dynamic tensile tests of hybrid fiber ECC coupon specimens are also reviewed to assess the effect of strain rate on the material uniaxial tensile behavior. The reviewed test results demonstrate the potential value of hybrid fiber ECC for providing better functionality as protective material in aspects such as increased shatter resistance with damage reduction due to scabbing and spalling, as well as significantly-improved cracking behavior, resistance against multiple impacts, and energy absorption associated with distributed microcracking in comparison to concrete.
