Prestressed carbon fiber plate strengthening technology is a kind of active reinforcement technology applied to bridge and long-span beam and other flexural members. It is popular because of its advantages of not increasing self weight and unloading.

Why is the prestressed CFRP different from the carbon fiber plate?

The main difference between the prestress CFRP plate and the ordinary carbon fiber strip is whether the prestress is applied. The prestressed CFRP plate can be passively reinforced into active reinforcement, which will make up for the strain lag of carbon fiber and make the new and old components work together to achieve better reinforcement effect.

In terms of material properties, prestressed CFRP is more superior in strength than ordinary carbon plate. In terms of construction, prestressed carbon slab construction is much more difficult than ordinary carbon plate construction. The application of prestressed carbon steel is more stringent, while ordinary carbon board is much simpler.
