Abstract: This paper investigates the bond strength between concrete and carbon fiber reinforced polymer (CFRP) sheet using three point bending test under Universal Testing Machine (UTM). Five different CFRP sheet thicknesses were used i.e. 200 GSM, 300GSM, 400GSM, 600GSM and 1.4 mm laminate. A total of 15 beam specimens were fabricated and tested to establish and compare the bond strength. It was found that 300 GSM thick carbon fiber reinforced polymer sheet has the highest bond strength. Values of bond strength show that while selecting carbon fiber reinforced polymer sheet thickness for any strengthening, retrofitting bonding behavior between element and carbon fiber reinforced polymer should be considered. Bond strength is not only dependent on the resin, but also on fiber thickness.

Key words: Bond strength, carbon fiber, thickness, concrete.
