Analytical study on the bonding method of carbon fiber sheets in the repair of corroded steel members

Abstract

This paper presents the applicability of CFRP adhesion for the repair of corroded steel members. To improve the strength of debonding, we carried out tensile tests and FE analysis that paid attention to the method of finishing up the ends of CFRP. As a result, it was confirmed that it was effective to the improvement of the strength of debonding to move the edge in the CF sheets. Moreover, the strength of debonding and the effect of the repair when patching to the section loss part of the steel member were verified. Based on these results, the repairing methods by CFRP adhesion were presented.
