At present, there are many carbon fiber products on the market. What troubles many friends is how to distinguish the authenticity of carbon fiber. It is really difficult for novices to distinguish, some imitation carbon fiber stickers, some use water transfer forms to pretend to be carbon fibers, the texture looks exactly the same as the carbon fiber texture on sports cars, so many friends think that they are buying real carbon fiber products Otherwise, it just has the same appearance but the internal structure is not real carbon fiber. How to check it?
Method 1: Distinguish from appearance and feel:
Fake carbon fiber products often use watercolor printing or stickers to forge the texture of carbon fiber, but the touch of carbon fiber cannot be achieved. The appearance of the product is mostly made of "twill" carbon fiber cloth and resin glue. The texture of the product has a clear sense of layering and 3D effects. The surface is smooth when touched by hand. Layered, even if it does, it does not have the smooth feel of real carbon fiber.
Even true carbon fiber has its advantages and disadvantages. It can be judged from the regularity of the texture and the brightness of the appearance. The uniformity of the corner gloss can be preliminary judged.

Method 2. Distinguish from weight:
In terms of weight, there is a kind of high imitation carbon fiber. At best, it is only made of glass fiber as the basic material, and the outside is covered with a sheet of imitation carbon fiber pattern. Some or spray black directly. But this "carbon fiber" imitation of glass fiber will weigh more than real carbon fiber.
For example, the following 3 keychains, the same style, different materials:
8.6g 10g 12g
Method 3. Use a blade to scrape the surface to identify:
Scraping with a blade: Real carbon fiber products will not scratch the carbon fiber itself. Because there is a layer of paint on the surface, only scratches will appear. If the UV surface paint is used, the hardness is strong and it will not scratch. Blade scraping can scratch a layer of stickers on the surface. For example, the following real carbon fiber clip is not bad, and can only scratch at most.
Method 4. Identify by fire:
Because carbon fiber has high temperature resistance characteristics, carbon fiber raw silk is not burnt. Here we take common carbon fiber wallet and luggage materials as examples:
The left is a fake carbon fiber luggage material, which has only a scorch smell when burned, and there is nothing left when it is burned, while the right material is real, and the carbon fiber raw silk will remain after burning, which is not bad.
Method 5. Disassemble and look inside the material:
Looking at the inside of the material, there is a very difficult way to distinguish the fake on the market. The middle part is glass fiber sandwich carbon fiber. The interlayer phenomenon can only be seen from the section, and it is difficult to distinguish the general method, and only the section can be seen.
Method 6. Identification with 40% -50% hydrochloric acid or sulfuric acid
Carbon fiber material has strong resistance to acid and alkali corrosion. Carbon fiber is a microcrystalline structure similar to graphite crystals formed by high-temperature graphitization at 2000-3000 ° C. This structure itself has high resistance to media corrosion, and can also be elastic in up to 50% hydrochloric acid, sulfuric acid or phosphoric acid. Modulus, strength, and diameter remained essentially unchanged.
Summary: Here are six methods for daily identification of true and false carbon fiber. I hope it will be helpful to everyone. Therefore, customers who are new to carbon fiber should find a professional carbon fiber manufacturer similar to lscarbongift to reduce procurement risks.
