The Five Points Of Carbon Fiber Products In The Molding Process Should Be Understood Clearly


When carbon fiber composite materials are produced into carbon fiber products, there are many processes to choose from. For example, compression molding is a particularly common carbon fiber product. Although the carbon fiber products of the compression molding process look relatively simple, if you don’t do it inside Knowing many problems, the performance of the produced carbon fiber products cannot be guaranteed. In this article, I will follow the editor of the Be-cu prototype to see the characteristics of the molding process.

 

In the molding process of carbon fiber products, the entire molding production efficiency is high, which is convenient for automatic production, and the surface of the entire carbon fiber product is smoother. Taken together, there are several aspects.

1. Pressure control during molding

In the molding process of carbon fiber products, pressure is a very important part. Under the action of pressure, the molding of carbon fiber products can be better. In the whole molding process, the pressure is to make the resin matrix in the carbon fiber prepreg flow better. The resin can be offset due to the pressure of the polycondensation reaction, which can well avoid swelling and delamination, and better ensure the overall structural stability and performance advantages of carbon fiber products. That pressure is also a very important place in the molding. When the fluidity is different, the speed of curing the resin inside and outside the carbon fiber product will be different. That is what needs to be paid attention to.

2. Control of molding temperature

The molding temperature is related to the entire molding situation of the carbon fiber product. The resin in the carbon fiber prepreg flows through the temperature, and then solidifies and molds. When the carbon fiber composite material is made at high temperature, the resin flows slowly, and the overall viscosity also slowly. When the temperature changes, the viscosity starts to change from large to small, resulting in a cross-linking reaction, and then as the temperature continues to increase, the cross-linking reaction gradually increases. The first reaction, that is, the first reaction when it comes into contact with the mold, this will cause the volatiles in the inner layer of carbon fiber to be excluded, which will affect the effect after molding. For example, if the curing temperature is too low, it will lead to a slow curing speed. In the case of low degree of curing. This also creates a difficult situation for carbon fiber products.

3. Molding time control

The time control during molding may not be very demanding, but it is a very critical place for actual product sales, because if you mold for a long time, it will lead to too long molding time, the actual production efficiency will drop, and energy consumption will be reduced. The higher the price of carbon fiber products, the higher the price of carbon fiber products. If the molding time is relatively short, it will lead to incomplete curing of carbon fiber products after molding, high roughness, and easy deformation, so the molding time also needs special attention. place.

4. Air and other volatiles

If there are air bubbles in the molding process of carbon fiber products, it will cause the surface roughness of carbon fiber products to be very high, so when we are molding carbon fiber products, we will emphasize that the carbon fiber prepreg must be compacted. Make sure that there is no air inside, so as to ensure that the surface finish of the carbon fiber products produced is higher.

These are all interpretations about the compression molding of carbon fiber products. The molded carbon fiber products have excellent performance, more structural stability, and can be mass-produced, but it is still a manufacturer of high-quality carbon fiber products. If necessary, welcome Everyone came to consult the editor of the Be-cu prototype. China Be-cu Prototype Material Technology Co., Ltd. has ten years of rich experience in the carbon fiber field.
