With the development of reinforcement and transformation industry, the existing structural strengthening systems can be basically satisfied, so new problems arise.

1. new technologies and new materials are few and few alternatives are needed.

2. traditional carbon fiber reinforcement has limitations and can not give full play to its performance advantages.

3. carbon fiber reinforcement effect is discounted?

4. do not want to use carbon fiber reinforcement, and do not use concrete reinforcement?

These problems do limit the development of reinforcement and transformation, and HM prestressed CFRP laminate reinforcement technology can solve these problems. 

• In the past, there is no good method for bridge reinforcement, and carbon fiber is always hard to use. The HM prestressed carbon plate can be cured by a strong tension, and can be cured two times in the later maintenance, save time and save cost.

• We should give full play to the high strength performance of the carbon fiber laminate and combine the old and new components together, to change the passive reinforcement into active reinforcement.

• Reducing cracks in original structures, or even eliminating structural cracks, essentially solves the problem of crack repair.

• It not only improves crack stiffness and crack resistance, but also increases the bearing capacity beyond imagination.
