Many people are surprised that a piece of carbon fiber cloth can play a powerful role on strengthening historical relics.

First of all, the tensile strength and elastic modulus of carbon fiber are higher than steel, which can effectively improve the bearing capacity, stiffness and seismic performance of building structures. 

Secondly, historical relics is often faced with the lack of seismic capacity. Carbon fiber wrap is made of a large number of carbon fiber, it is a ductile material. Externally bonded carbon fiber reinforced polymer(CFRP) wrap onto concrete may has good seismic performance. When the earthquake is coming, the carbon fiber cloth will connect the wall as a whole to absorb the energy of the earthquake release, delay the collapse of the house, and win more escape time for people.

In addition, historical relics is easy to corrosion at the root of the column because of the longer loading time and long-term weathering erosion. Therefore, for the historical relics, anticorrosion is a long and arduous task. The carbon fiber cloth and the epoxy resin adhesive used both have corrosion resistance. After retrofitting, the structure can be strengthened and can keep away from corrosion for a long time.

The strengthening of historical buildings must comply with the principle of preserving the original historical features. The carbon fiber cloth is light weight and easy to construct. It does not cause the damages to the structure, and basically does not increase the structural weight. It is a new advanced reinforcement method for the historic buildings.
