The purpose of this paper is to evaluate the structural capacity of Reinforced Concrete (RC) member retrofitted with Carbon Fiber Sheet (CFS) in order to improve the flexural strength. Eleven RC beam specimens are made and retrofitted with CFS by following the test objective. The main factor in selecting the test parameters is to verify the bond capacity of CFS. Therefore, parameters such as layer number of carbon fiber sheet, strengthening method, bonding ratio (100%-80%), and epoxy type are considered in the test. From the test, all specimens showed little bit different behavior each other. Especially, the flexural capacity was not linearly increased even if the layer number of CFS increased when it was more than two. Also the specimens with the low bonding ratio exhibited low strength as well as premature bond failure on comparing to other specimens.
