Abstract
The influence of discontinuous structural synthetic fibers (DSSF) on the bond-slip behavior between concrete and carbon fiber reinforced polymer (CFRP) composites was investigated using a double-shear pull-off test. The tested blocks were divided into three groups depending on the DSSF content. The CFRP composites were bonded to the blocks (with and without a CFRP anchoring strip) in three lengths (Lf): 50, 75, and 100 mm. For each Lf, three widths (bf) were used: 50, 75, and 100 mm. The results showed that: addition of DSSF to concrete slightly enhances the bond strength with CFRP composites, the pull-off force and slip increase with the increase in the CFRP bond length and width, and the use of CFRP anchorage strip improves the bond characteristics. The failure mode and bonding interface showed that as the DSSF increases, more concrete was attached to the peeled CFRP composite indicating that the concrete surface gets stronger.
