Is It Easy To Deal With Scratches On The Surface Of Carbon Fiber Products?

The texture of normal carbon fiber products will not be a problem. If the texture is damaged more, it cannot be repaired. If it is a slight texture damage, it can be repaired. It is also divided into matte and bright light. Scratches with bright light will be more difficult to repair.

Is It Easy To Deal With Scratches On The Surface Of Carbon Fiber Products

If there are slight scratches in the use of bright carbon fiber products, if they need to be repaired, it is first to roughen the surface of the carbon fiber to make the surface treatment carbon fiber rough, and then to facilitate the subsequent repair work. For polishing work, because the strength of carbon fiber products is very high, it is necessary to flatten the carbon fiber products during polishing, and the entire polishing surface is parallel to the polishing disc, so that the entire polishing surface can be stably polished on the rotating grinding disc. It is necessary to polish the center of the polished surface to the edge until the scratches on the surface of the carbon fiber product are polished, and the rough polishing is completed.

Carbon fiber products are used because of their performance. In addition to performance, the cleanliness and aesthetics of carbon fiber products are also very popular. In particular, carbon fiber patterns are a product that many friends who pursue personalized needs especially like. Many car modification parts are made of carbon fiber material, which has high requirements for the texture. Once the surface texture of the carbon fiber product is scratched, it is necessary to deal with the scratches, otherwise it will affect the actual price. As a china cnc machining manufacturer of carbon fiber products, Be-cu prototypes sometimes encounter carbon fiber products with scratches on the surface. How to deal with them? Let’s take a look.

Polished Finish

Scratches on the surface of carbon fiber can usually be treated by polishing. Polishing is a mechanical processing method that eliminates scratches on the surface through friction between the abrasive and the surface. Before carbon fiber polishing, the surface needs to be cleaned and smoothed with sandpaper. Then polish using gradually finer abrasive paper until the surface is smooth again. Note that when using polishing agent, you must choose a product suitable for the surface of carbon fiber to avoid causing greater damage to the surface.

Padding Processing

If the scratches on the carbon fiber surface are deep and cannot be treated by polishing, a filling method can be used. Filling can fill surface scratches and dents and make the surface smooth again. Generally speaking, the filling material should be similar to the carbon fiber material on the surface. First, filler material is applied to the surface, then smoothed with sandpaper, and finally polished. It should be noted that the filling material must be the same color as the carbon fiber material, otherwise it will affect the appearance.

Overwrite Processing

If the scratches on the carbon fiber surface are serious and cannot be repaired by filling and polishing, then you can consider using covering treatment. Covering treatment is to cover the surface with a thin film. After covering, the surface can be restored to smoothness without affecting the appearance. This method is suitable for situations where there are many or deep scratches on the surface that are difficult to deal with. It should be noted that the film material covering the treatment must be similar in color and texture to the carbon fiber surface, otherwise it will affect the appearance.

To sum up, there are many ways to deal with scratches on the surface of carbon fiber, including polishing, filling and covering. Different methods are suitable for different situations, and it is necessary to choose the appropriate treatment method according to the specific situation. In order to maintain the beauty and texture of the carbon fiber surface, it is recommended to seek professional advice before proceeding with treatment.

After rough polishing, it is to carry out fine polishing. Fine polishing is to use abrasive paste for polishing, and it is also necessary to add a suspension such as aluminum oxide for two-knife polishing. The normal process is to first use 2.5μm diamond suspension to sprinkle on. On the woolen cloth with medium fluff, add a suitable emulsified lubricant to reduce or avoid friction and wear, and polish it on the polishing machine for 2-3 minutes until the scratches caused by rough polishing are all removed. After polishing, rinse the polished surface with water or a solution containing a cleaning agent.

In this way, even if the entire polishing process is completed, the carbon fiber products after polishing are basically difficult to see scratches, and there will be no major problems. After the carbon fiber products are polished, carbon fiber repair technology needs to be used. This requires very good technical requirements and certain technology.
