Carbon fiber reinforcement includes carbon fiber cloth reinforcement and carbon fiber plate reinforcement. The research on the use of carbon fiber materials for concrete structure reinforcement and repair began in the 1980s in developed countries such as the United States and Japan.
This technology started very late in China, but with the rapid development of China's economic construction and transportation, a considerable number of existing buildings have historical problems due to the low design load standards at that time. Some buildings are difficult to meet the current standard use requirements due to changes in their use functions, and they are in urgent need of repair and reinforcement.
