This study investigates the effect of temperature on the behaviour of concrete cylinders wrapped with Carbon Fibre Reinforced Polymer (CFRP). The study used nine concrete cylinders in three groups; the first group was exposed to room temperature of approximately 20ºC, the second group was exposed to a cyclic temperature with a temperature range of 20ºC to 70ºC, and the third group was exposed to a prolonged temperature of 70ºC. All cylinders were then tested to failure. The study indicated that ultimate strength of cylinders wrapped with one and two layers of CFRP are significantly unchanged after being exposed to 20ºC to 70ºC and 70ºC. Deflection at ultimate load of cylinder wrapped with one layer of CFRP increased after being exposed 20ºC to 70ºC and 70ºC while for cylinder wrapped with two layers of CFRP increased after being exposed to 70ºC but significantly unchanged after being exposed to 20ºC to 70ºC. Ultimate deflection and total energy absorption of cylinders wrapped with one and two layers of CFRP decreased after being exposed to 20ºC to 70ºC and 70oC. Moreover displacement ductility of cylinders wrapped with one and two layers of CFRP increased after being exposed to 20ºC to 70ºC and 70ºC.
