To study the impact resistance of concrete confined with FRP jackets of large deformation, 32 concrete cylinders wrapped with AFRP, PEN and PET FRP composites were prepared and tested using the large-capacity drop-hammer equipment. The time history responses of the impact force were attained and analyzed. The experimental results revealed that the concrete confined by PEN and PET FRPs, which hold a large-rupture-strain (LRS) capacity, achieved superior impact resistance than that confined with AFRP in terms of the peak impact force. The increase of the jacket stiffness led to a significantly increase impact resistance of FRP-confined concrete.
