[0002] Carbon fiber reinforcement includes carbon fiber cloth reinforcement and carbon fiber plate reinforcement. Carbon fiber with extremely high tensile strength is pre-impregnated with epoxy resin to form a composite reinforcement material (unidirectional continuous fiber), and then attached to the structure to be reinforced along the tensile direction or perpendicular to the crack direction with epoxy resin adhesive to form a new composite body, so that the reinforcing adhesive material and the original reinforced concrete are subjected to force together to increase the crack resistance or shear resistance of the structure, and improve the strength, stiffness, crack resistance and elongation of the structure.
