There are many production and forming processes for carbon fiber products, such as the winding process and rolling process of carbon fiber circular tubes, and the carbon fiber square tubes and special-shaped carbon fiber products are more using the molding process, and the molding process is also commonly used by Nanono. Product production process, this article will follow the editor of Nanono to see the content about the modification process.

Compression molding is from the production and processing of plastic products. The molding process is mainly to complete the corresponding layup through the mold, and then process the carbon fiber products under the action of high temperature and high pressure. There are also many places that need special attention in the production process of carbon fiber products. , Because in the whole molding process, the production and processing of different products are still different. The molded carbon fiber products have very good performance advantages, and the overall accuracy of the product is also better, can be very good The efficiency of mass production is completed, and the surface flatness of carbon fiber products after molding is also better. These are the advantages of compression molding.

But when molding, there are three aspects to pay attention to:

First of all, the molding of carbon fiber products must ensure that the prepreg can be compacted when it is layered. Only compaction can better ensure that there is no air inside the layer after the layering. If there is more air, it will lead to carbon fiber after molding. Products are prone to cracking and delamination, so pre-compaction is a very important process when molding, especially for carbon fiber products with relatively thick walls. At this time, air must be mixed with air, so it must be compacted at this time. If it is not compacted, it will lead to the fact that after heating and pressurization, because the resin is relatively viscous, it will cause the bubbles to be unable to be discharged. affect the final performance.

The second is the pressurization of the carbon fiber product during molding. If the pressure is given, it is to make the resin flow more thoroughly, and the final dimensional accuracy of the carbon fiber product will also be better. If the pressure is too fast, it will easily lead to The resin content in carbon fiber products is low, which ultimately affects the actual shear strength. If the pressure is too late, it may lead to inconsistent internal and external curing of carbon fiber products. The final situation is also carbon fiber products because the resin is not uniform enough. It appears that there is a difference in the complete performance of the product.

The other is the control of heating and heating. The heating is to make the resin of the carbon fiber product inside the carbon fiber melt first, then melt and then solidify. If the heating speed is faster, it will easily lead to premature heating of the carbon fiber product, which will eventually Inconsistent flow of internal and external resins will also affect the final product performance. If the heating is too slow, the working efficiency of compression molding will be too low, which will lead to an increase in production costs, and the invisible will also make the price of carbon fiber products much higher.
