Carbon fiber reinforcement technology is a new reinforcement method by bonding carbon fiber sheets to reinforced components. Carbon fiber sheet has the advantages of high strength, high elastic mode, light weight and good corrosion resistance. It is a very promising reinforcement method.Fiber-reinforced composite reinforcement repair technology can be applied to a variety of structural types (e.g. buildings, structures, bridges, tunnels, etc.), a variety of structural shapes (e.g. rectangles, circles, curved structures, etc.), various structural parts (beams, plates, columns, arches, crucibles, etc.), without changing the structure shape and does not affect the appearance of the structure. The reinforcement and repair of buildings due to fire, corrosion and other damage is especially suitable for the structural reinforcement and improvement of existing structures due to local changes in design use.
