The emergence of prestressed FRP laminate has greatly helped solve the FRP strengthening problems. The biggest breakthrough of prestressed FRP laminate is to completely change the characteristics of passive reinforcement of materials, and play an active role in strengthening the structure by prestressing technology.

The carbon fiber reinforcement method is not suitable for the reinforcement of concrete structures due to insufficient rigidity, excessive deformation, and normal use limit conditions. When used for torsion reinforcement, although it can play a certain role, it is not economical and needs to be determined through further experimental research.

The prestressed CFRP laminate system is different from the prestressed steel strand system. It is a bonded prestressed reinforcement mode. The anchorage only bears the prestressing effect when the tension is completed, and the stress load depends on the connection and transmission between the carbon fiber sheet glue and the target structure.
