1. All incoming materials, including carbon fiber materials and bonding materials, must comply with quality standards and have factory product certificates, meeting the requirements of engineering reinforcement design.

2. Carbon fiber materials should not be compressed during transportation and storage to prevent damage to the carbon fibers, nor should they be directly exposed to sunlight and rain. Adhesive materials should be stored in a cool and sealed manner.

3. The construction quality of each process shall be guided and supervised by technical personnel. After each process is completed, it shall be submitted to the technician for inspection and approval before proceeding to the next process.

4. Apply bottom coat paint

The coating should be evenly applied and not missed. It is strictly prohibited to apply under unsuitable temperature conditions. The coating diluted with solvents should be used up within the specified time.

When the temperature is below 7 ℃, the relative humidity RH is less than 85%, the surface moisture content of concrete is below 8%, and there is no condensation phenomenon, modified epoxy resin must be used.

5. Surface damage repair of components

Small holes and interior corners on the surface of the structure must be repaired and leveled with epoxy putty. Any unevenness or roughness that still exists on the surface after applying putty should be smoothed with sandpaper.

6. Paste carbon fiber

① When pasting carbon fiber materials, the following conditions must be met:

a、 Carbon fiber materials should be cut according to regulations.

b、 The temperature, humidity, and surface moisture content of the components meet the requirements.

c、 The bottom coating and putty have reached finger touch drying (the resin surface has solidified and hardened).

d、 The type of bonding resin should be suitable for the temperature during construction. The main agent, curing agent, and curing accelerator should be accurately weighed according to the specified ratio, loaded into a container, and stirred evenly with a mixer. The amount of each mixing should be used up within the specified time.

② Quality inspection standards for carbon fiber bonding.

a、 The bottom coating and top coating are well immersed in carbon fiber bundles.

b、 Carbon fiber is tightly bonded.

c、 For hollow drums with a diameter of 10mm to 30mm, less than 10 per square meter can be considered qualified; If there are more than 10 per square meter, it is considered unqualified and needs to be repaired. For hollow drums with a diameter of over 30mm, any occurrence is considered unqualified and requires repair.

d、 The overlapping length along the fiber direction shall not be less than 20cm, and the overlapping parts between each layer shall not be located on the same straight line. The layers must be staggered by at least 50cm.

e、 The specifications, pasting position, length, width, fiber direction, and number of layers of carbon fiber materials comply with regulations.
