When it comes to the construction of carbon fiber cloth reinforcement, I believe that those engaged in reinforcement work are somewhat familiar with it. It is a new type of reinforcement method that has been widely used in recent years. However, during the construction of carbon fiber cloth reinforcement, there are many seemingly insignificant details that are easily overlooked, yet these small details play a very important role in the entire reinforcement project. Today, let me take you to understand them in detail:
Before the construction of pasting carbon fiber cloth, it is necessary to clean the surface of the base material of the reinforced structure. Many reinforcement workers tend to neglect this step. If dust, oil stains, loose materials and other debris on the surface of the base material are not cleaned thoroughly, it will affect the bonding strength between the carbon fiber cloth and the base material, and subsequently lead to significant differences in the reinforcement performance of the carbon fiber cloth.
When pasting carbon fiber cloth, the selection of reinforcement materials is also important. It is recommended that the carbon fiber cloth and the impregnating adhesive be selected from the same manufacturer. Because the impregnating adhesive produced by the same manufacturer will develop a matching carbon fiber impregnating adhesive according to the ductility of the carbon fiber filaments, which has good bonding matching performance and can greatly improve the tensile strength of the carbon fiber cloth.
When pasting carbon fiber cloth, paste the cut carbon fiber cloth along the force direction according to the requirements of the relevant design drawings, and use tools such as rollers or scrapers to squeeze from the middle to both sides along the fiber direction to remove air bubbles and make the carbon fiber cloth closely adhere to the base layer.
When pasting multiple layers of carbon fiber cloth, the adhesive should be applied on the surface of the previous layer of carbon fiber cloth before pasting the next layer. The pasting directions of adjacent two layers of carbon fiber cloth should be perpendicular to each other.
After the carbon fiber cloth is pasted, it needs a certain period of curing and maintenance. During this period, attention should be paid to maintaining the temperature and humidity of the construction site, avoiding direct sunlight and rain erosion. And spread a layer of yellow sand. After spreading the yellow sand, the surface will show a rough texture, which can increase the contact area between the surface of the carbon fiber cloth and the decorative surface layer, thereby improving the bonding firmness of the surface of the carbon fiber cloth and facilitating the construction better.

Construction Process of Carbon Fiber Cloth:
Base Material Treatment: Use a grinder or sandpaper to grind the base surface, remove the loose concrete layer until the solid base surface is exposed.
Mixing Carbon Adhesive: Mix the carbon fiber impregnating adhesive in a reasonable proportion of A:B = 2:1.
Cutting Carbon Cloth: Cut the carbon fiber cloth according to the design requirements and the size of the base surface to be pasted on site according to the specified size.
Applying Carbon Adhesive: Use a roller to evenly apply the evenly mixed carbon fiber adhesive on the surface of the base layer of the part to be pasted.
Pasting Carbon Cloth: Paste the cut carbon fiber cloth along the force direction according to the requirements of the design drawings.
Secondary Rolling: Repeat the process of applying the impregnating adhesive again to ensure that the carbon fiber cloth is completely soaked in the resin.
Static Maintenance: After the carbon fiber cloth is pasted, curing and maintenance are required to ensure the bonding strength.
Summarizing Carbon Fiber Cloth Reinforcement
Although these details seem insignificant, if they are ignored, the performance of the carbon fiber cloth reinforcement project may be greatly reduced. Therefore, each detail deserves our sufficient attention during the construction process. Only in this way can we ensure the success of the carbon fiber cloth reinforcement project and safeguard the safety of buildings.
