5. Carbon Fiber Fabric Directions for Use
1. Before pasting carbon fiber, the related direction work such as cleaning of structural surface attachments and chiseling of paint layer should be completed, and the solid structural surface of the component must be exposed.
Grind off the surface of the structural components of the floating pulp layer, burrs, stains, etc., to ensure that the structure surface is smooth and clean, the positive corner of the components should be polished into a radius of not less than 20mm small rounded corners, after the grinding is completed, with a strong hair dryer for detailed cleaning treatment.
2. Chiseling and repair the original structural surface.
Repair materials such as structural adhesive or 42.5# cement to smooth the surface to ensure that the structural surface of the components is smooth and without cracks, so as to facilitate the smooth transition of carbon fiber cloth.
3.Test and paste the position line
According to the design requirements of the drawing, paste the position line.
4. Carbon fiber cloth cutting
According to the requirements of the drawing, the actual section size and span (length) of the reinforced component were measured on site.According to the cutting list, the cutting construction of carbon fiber cloth was completed. Carbon fiber cloth should be placed on a flat, clean and solid plane for blanking to avoid contamination and minimize blanking errors.
5. Mixing the Carbon fiber adhesive according to the mixing ratio,ensure that the AB group are evenly mixed
6. Apply the epoxy resin adhesive
Use a plastic scraper or roller to evenly apply the prepared epoxy resin adhesive on the surface of the component, the adhesive layer must be uniform, full, no bubbles, when applying epoxy resin adhesive, the structural surface of the component must be dry if the moisture content of the
component surface is greater than 4%, measures should be taken to dry.
7. Paste carbon fiber cloth
Paste the carbon fiber cloth from one end to the other, adhesive surface covered with epoxy resin adhesive, and scrape the carbon fiber cloth with a scraper along the direction of the fiber,force until the epoxy resin adhesive is completely soaked in the carbon fiber cloth to ensure that the carbon fiber cloth and the structural surface are tightly pasted.
8. Within 1 hour after the carbon fiber cloth is pasted, apply epoxy resin adhesive or paste the second layer of carbon fiber cloth, track and check the paste quality. If the surface of the carbon fiber cloth needs covert processing, it should be sprinkled with sand and roughened within 30-45 minutes after applying the epoxy resin adhesive.
9. Static curing
Within 2 hours of pasting the carbon fiber cloth, no disturbance is allowed, and the component should not be loaded within 3 days.
10.Inspection and acceptance After the construction of carbon fiber cloth paste is completed, paste quality inspection and acceptance should be carried out 7 days later. According to the requirements of the code, the carbon fiber cloth paste hollow drum ratio (the ratio of the total hollow drum area to the total paste area) is not greater than 5%.
11.When the temperature is below 5 ° C, heating measures can be taken or the mixing ratio of the adhesive can be adjusted appropriately to ensure the paste quality of the carbon fiber cloth.
