Carbon fiber wrap reinforcement in bridge reinforcement

For the reinforcement of bridge buildings, the use of carbon fiber wrap should first be immersed in epoxy resin to form strong sheet materials. Then the epoxy resin is bonded in the direction of cracks according to the direction of force. When the component is subjected to tension load, the crack will not be further cracked along the direction of force through the role of fiber sheets. Thus, it can reinforce the main body of the building and ensure the stability of the structure at the same time.
