Carbon fiber is the representative of high-performance materials at the present stage. The reason is that carbon fiber materials have very good strength properties. In practical applications, the advantage of lightweight is that carbon fiber materials can better replace traditional metal products. The advantages of the lightness of the product, in some special environments, there are also high requirements for the corrosion resistance of the material, so is the carbon fiber corrosion resistant? This article will follow the editor to take a look.
The corrosion resistance of carbon fiber is very high. This is because the structural stability of the broken fiber has a lot to do with it. The production of carbon fiber material needs to be refined under thousands of C to remove the internal impurities and carbon elements. The process of lithification forms a carbon microcrystalline structure. This material structure has the advantage of very high medium corrosion resistance. In the environment of 50% hydrochloric acid or sulfuric acid phosphoric acid, the entire mechanical properties are modeled in detail. Including the diameter of the legs will not change greatly, which also brings very good performance advantages to the erosion resistance of the fiber material. This ensures that carbon fiber exhibits a very good advantage in corrosion resistance.
It can be seen that carbon fiber has a very high corrosion resistance performance. But for carbon fiber products, this is not necessarily the case, because pure fiber cannot be independently produced into carbon fiber products. If it needs a matrix material, the common one is resin matrix material, and the corrosion resistance of carbon fiber products is just like that of resin. The matrix itself and the contact surface between the resin and the carbon fiber also have a lot to do with it.
Therefore, the performance of this carbon fiber product is very different from that of the resin matrix, and it will also have different performance in different environments and different application environments. For example, common resin-based carbon fiber products have very good corrosion resistance performance, and can have good corrosion resistance performance in various environments, and the overall weather resistance is relatively good, but if it is in a hot and humid climate area , compared to the inland environment, it will age faster. Including the daily use of carbon fiber products, under the sun’s rays and the comprehensive application of ultraviolet rays, the corrosion often starts from the surface corrosion. When we produce longtan fiber products, in order to better ensure the durability Corrosion resistance, often means that the surface is treated with oil and coated with transparent paint, which can better ensure the corrosion resistance of carbon fiber products.
In order to better ensure the corrosion resistance of fiber products, the number of matrix materials is often to choose resins with macromolecular structures containing body structures, benzene rings, and heterocycles, and hydrogen sugar crystalline polymers can be formed between molecules. The matrix is a good choice for enhancing the corrosion resistance of carbon fiber composite products. In practical applications, the interface between resin and carbon fiber is also a key point that affects corrosion, so the coating of carbon fiber products can also effectively improve corrosion resistance and avoid the intervention of moisture or harmful media.
In addition, during the production process of carbon fiber products, we also pay attention to their porosity or structural defects, including compaction treatment, which can make the penetration of corrosion substances include diffusion, which is also an important treatment for our manufacturers to improve the corrosion resistance of carbon fiber products. Way.
On the whole, the corrosion resistance of carbon fiber is very good. Then I say that the overall corrosion resistance of fiber products is related to the base material including the actual production and processing process. If there are requirements for the corrosion resistance of carbon fiber products, It is necessary to find high-quality carbon fiber product manufacturers, so as to better ensure the corrosion resistance requirements of carbon fiber products.
