Fiber-reinforced polymer (FRP) composites have been used for decades in aerospace and manufacturing applications where low weight high tensile strength and corrosion resistance are desirable properties. The use of such systems has been implemented in both new construction and for repair and rehabilitation of existing structures. In most cases rehabilitation of existing structures occurs due to concrete spalling caused by extensive rebar corrosion. It has been shown through numerous experimental and analytical studies that externally-bonded FRP composites can be applied to not only improve structural performance criteria but also the durability of members. The purpose of this report is to report test data of performance of concrete beams and columns which have been damaged prior to repair is with FRP. Two types systems were tested: epoxy and polyurethane based carbon fiber system. Results show that both systems behave very similarly.
