The study focuses on the improvement of the cohesion strength of CFRP-to-substrate bonded joint by means of mechanical anchors built with the same fibers as the composite and plugged, in the substrate, like ‘‘nails’’. Research on the use of this typology of anchor for masonry substrates has been limited. The aim of this study is to provide experimental data to quantify the efficiency of the carbon fiber anchors on the strength of a reinforced brick. The research demonstrates that the use of CFRP anchors increases the resistance and the dissipation capability of the reinforcement if the anchors are properly placed.

Abstract

The study focuses on the improvement of the cohesion strength of CFRP-to-substrate bonded joint by means of mechanical anchors built with the same fibers as the composite and plugged, in the substrate, like ‘‘nails’’. Research on the use of this typology of anchor for masonry substrates has been limited. The aim of this study is to provide experimental data to quantify the efficiency of the carbon fiber anchors on the strength of a reinforced brick. The research demonstrates that the use of CFRP anchors increases the resistance and the dissipation capability of the reinforcement if the anchors are properly placed.
