Advantages of Carbon Fiber Reinforced Polymer(CFRP): 1. The one-way tensile strength is high, which is about 7-10 times than steel. 2. It is light in weight and only 1 / 4 weight of the steel, which can be operated manually without large machines and equipment; it is pasted on the surface of the structure, with fast construction speed and short period, which has little impact on the life and production of the reinforced structure, and hardly increases the quality of the original structure. 3. Carbon fiber strengthening system is with high modulus of elasticity, can play an important role in strengthening of concrete/steel. 4. It is stable in humid and corrosive environment, and can resist the corrosion of acid, alkali, salt and water because of the stable chemical properties of fiber reinforced composite and resin bonding. 5. Carbon fiber strengthening system is widely used in bridges and other projects,like building beams, columns and floors,tunnels and chimneys,municipal roads,steel pipes,etc; The onstruction performance is superior, easy to cut, and has a high adaptability to the required shape and size. 6.Carbon fiber strengthening system is an economic and effective method for concrete crack reinforcement and foundation repair, and also suitable for repair and reinforcement of pipeline cracks and corrosion.
