Effects of fiber sheet reinforcement on the explosiveresistant

Abstract

This study evaluates the effectiveness of fiber sheet reinforcement on the 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 failure modes of concrete plates subjected to contact explosion, and formulae proposed by McVay and Morishita et al. have been applied to estimate these failure modes taken in the tests. To examine the reinforcing effect by fiber sheets on the local damage and fragmentation of concrete plates, contact explosion tests have been conducted. The local damage of concrete plates reinforced by carbon or aramid fiber sheets have been extremely reduced as compared with that of concrete plates without fiber sheet reinforcement. These fiber sheets are also effective to prevented concrete plates from fragmentation.
