摘要：

The present work is intended to evaluate 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 existing formulae have been applied to estimate these failure modes taken in the tests. To examine the reinforcing effects 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 sheet 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. (C) 2008 Elsevier Ltd. All rights reserved.
