CFRP fabric, good choice for bridge reinforcement
The carbon fiber fabric(CFRP) reinforcement and repairing concrete structure is a newly developed reinforcement technology in recent years. It has many advantages such as simple construction, strong adaptability and chemical corrosion resistance. It has been applied in bridge engineering.

New technology of highway and bridge reinforcement
They are mainly some special reinforcement measures formed through the innovation of materials and construction methods. The main reinforcement measures are composite reinforcement technology (FRP).

Why Carbon Fiber Reinforcement and Retrofit is so Hot
Carbon fiber reinforced repairing technology is another new type of structural strengthening technology after increasing concrete section and sticking steel. Carbon fiber reinforcement was first introduced into China from Japan, the United States and other developed countries, but due to its unique advantages, it has rapidly developed into the most common reinforcement method.

Complete process of CFRP retrofitting
The purpose of bonding CFRP wrap is to reinforce the engineering structure. The construction precautions are: the direction of force must be determined. The direction of bonding fibre cloth is consistent with the direction of force and can not be mistaken. Fiber cloth must be laid flat, not fold, not bend. The impregnating glue must be soaked by special rolling wheels and the air bubbles must be eliminated.

Comparison of Main Reinforcement Methods of Bridges
Using reinforcement method to strengthen and maintain the original bridge not only saves a lot of construction funds, but also solves the contradiction between the bearing capacity of the bridge and traffic demand in a short time. At present, the main methods used to reinforce bridges include enlarging section and reinforcing steel bar, bonding steel plate, external prestressing and carbon fiber sheet.

Stress Analysis of Bridges Strengthened with CFRP
Bridge belongs to a long-span structure, and the environment is relatively bad. Which method to maintain the bridge has become a difficult problem. After the research and development of science and technology, a new kind of material for bridge reinforcement - carbon fiber composite has emerged.
