The overall material strength of carbon fiber materials is not only high, but also has a very low density, which makes carbon fiber products outlaw traditional metal products in many fields, and has a very good lightweight effect. Carbon fiber tubes are very common products. One, there are a variety of molding processes in the molding of carbon fiber tube products. Carbon fiber tube manufacturers choose according to their actual conditions. Here is a look at the comparison between winding molding and pultrusion molding.
Pultrusion process
Carbon fiber tube pultrusion is a relatively common production molding method. This is also a common processing technology for other carbon fiber tubes. It can complete the production of carbon fiber tubes of various shapes and specifications. The whole process is to first impregnate the carbon fiber with resin, and then pass through Equipment, there is a corresponding mold on the equipment, there is a mandrel in the middle of the mold, and then the carbon fiber prepreg impregnated with resin is pulled to pass through the mold of a fixed size, and then heated to make the internal resin matrix block speed superglue Cured and then pulled out, it is a carbon fiber tube with a wall thickness between the mandrel and the mold.
If you have a little understanding of this production process, you will know that pultrusion can theoretically produce unlimited lengths of carbon fiber tubes, but in the same way, it does not need to be too long, because transportation is also a problem. In addition, this kind of pultrusion Extrusion is more straight-through carbon fiber products, that is, square tubes, round tubes, and I-shaped tube products, and the laying direction of the internal fiber tows is the same direction, so it has a very good axial direction. performance. But the performance will be weaker in the horizontal direction, which is where attention should be paid. The overall production efficiency of the pultruded carbon fiber tube is high, and the labor cost is low. It is an important tube forming process that carbon fiber product manufacturers will choose.
roll forming process
The roll forming process can be said to be the forming process of the product changed from winding forming and compression molding. Carbon fiber prepreg is used. First, the mold of the pipe size is prepared, and then the carbon fiber prepreg is cut according to the size of the pipe. , and then use the winding machine to wind the carbon fiber prepreg layer by layer onto the mold. A layer of carbon fiber prepreg needs to complete a complete round of rolling. Then there will be ±45 depending on the angle. The lay-up design can make the pipe have good performance under various stresses.
Therefore, in the production and processing of carbon fiber tube winding, the angle layup design of carbon fiber prepreg is first carried out according to the use requirements of the tube, and then the cutting of the prepreg is carried out. The overall specification of the carbon fiber tube after production
The carbon fiber tubes made by roll molding process also have advantages. The advantage lies in the high production efficiency, no need to impregnate again, and the continuous production of tubes through multiple molds. The applications include carbon fiber man-machine frame, carbon fiber robot arm, carbon fiber mixed shaft, etc., including this kind of one. If you pursue the appearance and size of the pipe, you can also lay a layer of carbon fiber single-layer prepreg with better texture on the outer surface.
The above two points are related to the interpretation of carbon fiber tube pultrusion and roll forming. Under different production processes, the production of carbon fiber tubes can be well completed. Of course, the price of carbon fiber tubes in different processes will also vary. There is a slight discrepancy, and the purchase of carbon fiber tubes is more based on the actual situation of your own products. Of course, if you need it, you are welcome to come to consult us.
