CFRP reinforced concrete structures
Carbon fiber reinforced polymer ( CFRP) sheets reinforcement is a new type of method of structural reinforcement，which be- longs to the method of FRP composite strengthening system. In recent years, CFRP with light weight，high strength and anti － corrosion had been widely used in strengthening the reinforced concrete structure

FRP composite strengthening the steel structures
The strength of the FRP composite is high. In order to achieve the same reinforcement effect, the size of the FRP composite material is obviously smaller than the size of the steel plate. After FRP reinforcement, the dead weight of the original structure and the size of the original component are basically not increased.

How to solve the prodblem use prestressed FRP laminate?
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.

Carbon fiber fabric for torsion strengthening
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.
