Experimental and analytical study of steel plate bonding CFRP plate with thin adhesive layer

Abstract

There is a method of bonding CFRP plate as a repair method for steel structures. In order to reduce the stress of the steel plate, it is necessary to bond the CFRP plate with sufficient bonding length. By reducing the thickness of the adhesive layer, the bonding length can be shortened. Test specimens in which CFRP plates were bonded to both sides of a steel were prepared and subjected to static tensile tests. We studied the bonding length when the adhesive layer is thin by finite element analysis modeling the test specimens.
