The Production Process Of Carbon Fiber Board

Carbon fiber sheet is the most initial and basic application form of carbon fiber direct connection in many fields. As a basic carbon fiber product, it has a series of advantages such as light weight, high strength, corrosion resistance, and high working temperature. The editor of the Be-cu prototype in this article gives Let us introduce the production process of carbon fiber board.  

The Production Process Of Carbon Fiber Board

First, the prepreg is cut according to the specifications of the required sheet. The raw material width of the prepreg is fixed. If the original size is not enough, then the splicing of the material is involved. For non-conventional size sheets, a reasonable design must be carried out before the prepreg is cut.

Through the optimization of the design, the prepreg is maximized, the generation of edge margins is reduced, and the production cost is reduced. Then there is the layup of carbon fiber prepreg. The commonly used layup angles are 0°, 90°, ±45°.

Carbon fiber is an anisotropic material. Different angles show different properties, which is also the difference between carbon fiber and other One point of material, it can give full play to its advantages through reasonable lay-up design.

Carbon fiber panels have good overall performance and play a very important role in high-end fields such as aerospace. The production of carbon fiber panels is more difficult and requires higher experience and equipment from the prototype manufacturer.Be-Cu prototype has been producing carbon fiber products for more than 30 years. We can use our own experience to introduce some knowledge to everyone.

The Manufacturing Process Of Carbon Fiber Panels

Carbon fiber boards are mostly made of carbon fiber composite prepreg. If you want to produce carbon fiber boards with composite requirements, the raw materials must be selected well, and then it depends on the production process.

  • Cut the prepreg: According to the drawings, cut the carbon fiber prepreg into appropriate length and width. Usually the thickness of the prepreg is about 0.2mm, and then cut the corresponding quantity according to the thickness of the carbon fiber plate. of carbon fiber prepreg.
  • Prepreg layup: The size and quantity are appropriate. The next step is the most important step in the carbon fiber board production process, which is the layup. Laying is not a layer cake, just fold it in half. The prepreg needs to be laid in different directions so that the positive pressure in different directions remains the same. Usually there are 0°, ±30°, ±45° and 90° available, usually using a mixed layup method.
  • High-temperature curing and molding: After the carbon fiber prepreg layering is completed, only the prototype of the carbon fiber board is formed, which still needs to be put into the autoclave for high-temperature curing and molding. At this time, the carbon fiber board has basically been finalized. Carbon fiber prepregs of different materials require different temperatures, pressures and times.
  • Polishing treatment: Take the carbon fiber plate out of the autoclave, cut off the excess edges, and polish the surface to remove impurities and dirt to keep the surface smooth and smooth. Grinding is divided into rough grinding and fine grinding. In addition, painting or drilling operations are required, and appropriate equipment needs to be selected for processing.

Delamination Occur During The Production Of Carbon Fiber Panels

Don’t look at the above introduction to the carbon fiber plate manufacturing process. It seems that you can get started after reading it. In fact, various problems and details emerge one after another during the process. Only by solving these problems and perfecting the process in the details can we ensure the carbon fiber The quality of the board is passable. When we first produced carbon fiber boards, there was a problem of carbon fiber board delamination. What caused this?

After the carbon fiber prepreg is cut and laid out in an orderly manner, it enters the baking and curing stage. After the prepreg is heated and pressurized in the mold, the hot-pressing mold is closed, allowing the laminated material to gradually solidify under heat and pressure. However, this If there is insufficient pressure during the process, the carbon fiber panels produced will easily delaminate.

In fact, it is not only pressure, but also temperature and time. These three factors must be controlled in the molding process. In the processes such as lamination, rolling, and post-processing, there are dozens of factors that need to be taken into consideration. So making carbon fiber panels is not as easy as it seems.

The last step is the curing of carbon fiber prepregs. After all the prepregs are layered, they need to be sent to a press for curing under high temperature and high pressure. After the carbon fiber board is cured and formed, in order to use the requirements, post-machining such as laser cutting and drilling are generally required to meet the required requirements.
