Carbon fiber reinforcement comprises carbon fiber and carbon fiber reinforced STRENGTHENED two kinds.

Carbon fiber materials for reinforcement of concrete structures repair began in the 1980s the United States, Japan and other developed countries. Of this technology started late, but with the rapid development of China's economic construction, and transportation infrastructure, a significant portion of the existing building at that time due to the low standard of design load caused by historical issues, the use of some of the buildings change function, it is difficult to meet the current specification needs to use the urgent need for repair, reinforcement.

There are many commonly used reinforcement methods, such as: increasing section method, Outsourcing Steel Reinforcement, bonded steel reinforcement method, carbon fiber reinforcement method. Carbon fiber reinforced repair structure technology is the second increase concrete sections, a new type of structure steel reinforcement technology sticky after.
