Abstract

The present work is intended to evaluate the effectiveness of fiber sheet reinforcement on explosive-resistant performance of concrete plates. Carbon fiber sheets or aramid fiber sheets have been employed to reinforce concrete plates. Explosion tests have been conducted to examine the effect of fiber sheet reinforcement on local damage and fragmentation of concrete plates. Test data are compared with the estimated values formulated by Morishita et al. and the characteristics of local damage are discussed. Local damage of concrete plates reinforced by carbon or aramid fiber sheets has been extremely reduced as compared with that of concrete plates without fiber sheet reinforcement. These fiber sheets also have prevented concrete plates from fragmentation.
