1) compared with the direct bonding of carbon fiber, the prestressed CFRP strip system can not only effectively utilize the high strength of carbon fiber, save the amount of carbon fiber, reduce the total cost of the project, but also inhibit the deformation and crack development of the component, effectively improve the bearing capacity of the concrete structure, and improve the mechanical performance of the concrete structure.

2) compared with other pre-stressed carbon fiber reinforcement systems at home and abroad, the prestressed CFRP anchorage system is specially designed for the characteristics of bridge reinforcement. It has excellent static load anchorage performance and fatigue resistance, can apply higher prestress, further exert the strength of material, and improve the bearing capacity of the bridge.

3) carbon fiber composites have remarkable characteristics such as high strength, light weight and corrosion resistance. It does not increase the weight of the original structure, does not affect the use of the original structure, and does not leave traces after reinforcement.

4) fast construction, no wet operation, no need for large construction machinery, and less occupation for construction.
