Carbon fiber reinforcement includes carbon fiber cloth reinforcement and carbon fiber board reinforcement. The research on carbon fiber materials used in the reinforcement and repair of concrete structures began in the developed countries such as the United States and Japan in the 1980s. China's technology started very late, but with the rapid development of China's economic construction and transportation industry, a considerable part of the existing buildings caused historical problems due to the low design load standards at that time. Some buildings are difficult to meet due to changes in the use of functions. The requirements of the current specification are in urgent need of maintenance and reinforcement. There are many commonly used reinforcement methods, such as: increased section method, steel reinforcement method, bonded steel reinforcement method, carbon fiber reinforcement method, etc. The carbon fiber reinforcement repairing structure technology is another new type of structural reinforcement technology after increasing the concrete section and sticking steel.
China began to introduce carbon fiber composite reinforced concrete structure technology from abroad in 1997. It has become a hot spot for research and engineering applications. Dozens of universities and research institutes in China have carried out this research work and have obtained a number of research results close to the international advanced level. As China has the world's largest civil construction market, the application of carbon fiber reinforced building structures will continue to grow.
