300 g CFRP unidirectional carbon fiber models to increase compared with traditional concrete sections or concrete bonded steel reinforcement, space-saving, simple construction, no fixed-site facilities, construction quality assurance and easy, the basic structure without increasing the size and weight, corrosion resistance, durability and other characteristics. In addition, using this construction method can greatly improve the life of the building, reducing the cost of reinforcement. Therefore, carbon fiber as a reinforcing material landmark, has become widely accepted and attention. (1) high tensile strength, is 7-10 times the same cross-section steel. (2) Light weight, density is only 1/4 of ordinary steel. (3) durability, corrosion and harsh environments can impedance, climate change, chemical damage. (4) construction of convenient, time-saving section, ease of construction quality assurance. (5) for a wide range of concrete structures, steel structures, wooden structures can be reinforced. Can greatly improve the carrying capacity of components, seismic performance and durability. Yixing Ding Weaving Co. ___ unidirectional carbon fiber 300 g CFRP models
