Most of the historical and cultural buildings in our country are mainly wood structures. Therefore, wood structure is the main structural form we face when strengthening ancient buildings. Many people are surprised, why a piece of carbon fiber cloth can play a powerful role in strengthening historical buildings?

First of all, the tensile strength and elastic modulus of carbon fiber materials are higher than that of ordinary steel, which can effectively improve the bearing capacity, rigidity and seismic performance of the structure of the building. This is the basis for carbon fiber materials to be used for the reinforcement of ancient buildings.

Secondly, wood structures often face the problem of insufficient earthquake resistance due to their own weaknesses. Since carbon fiber cloth is woven from a large number of carbon fiber bundles, it is a ductile material. The carbon fiber cloth is pasted on the wall and has good seismic performance. When an earthquake comes, the carbon fiber cloth will connect the wall as a whole to absorb the energy released by the earthquake, delay the collapse of the house, and buy more time for people to escape.

In addition, for the wooden structure, due to the long load time and long-term weathering erosion, corrosion at the root of the column is prone to occur. Therefore, anti-corrosion is a long-term and arduous task for wooden structures. The carbon fiber cloth and the matching epoxy resin adhesive are both corrosion resistant. After being compounded, the wooden structure can be reinforced and kept away from corrosion for a long time, which can achieve two results with one stone.

The reinforcement of historical buildings must abide by the principle of preserving the original appearance of history. Carbon fiber cloth is light in weight, easy to construct, does not cause secondary damage to the structure, and basically does not increase the weight of the structure. It is an ideal reinforcement method for the reinforcement of historical and cultural relics. It can perfectly comply with the repair principle of "repair the old as the old and preserve the status quo".
