How To Do The Layup Design Of The Carbon Fiber Tube In The Roll Forming Process

How To Do The Layup Design Of The Carbon Fiber Tube In The Roll Forming Process

In the production process of carbon fiber tubes, there will be different production processes depending on the shape of the tubes. For china cnc machining manufacturers, more production processes with high production efficiency and stable product performance will be used, and rolling will be used. The molding process, the knowledge of the roll-formed carbon fiber tube layup will be explained in this article.Compared with the winding molding process, the carbon fiber tube roll forming process has a more uniform distribution of resin.The carbon fiber prepreg is used, which has more performance advantages, but its shortcomings are not as good as the winding molding, such as the angle of the carbon fiber filament. It is not as good as the wound carbon fiber tube.

In order to further reduce its shortcomings, there is a layup design of the carbon fiber tube to further improve the performance of the carbon fiber tube. When laying layers, pay attention to such knowledge.

The Thickness Of The Layup Determines The Design Of The Layup

In the production and machining of carbon fiber tubes, the first thing to pay attention to is the wall thickness of carbon fiber tubes. The thickness of the wall is an important way to determine how many layers of carbon fiber tubes can be laid. , how to carry out the layering design is very critical. From the production and machining process, continuous layering is definitely a direct way to save costs and efficiency, but under the practical problems of carbon fiber continuous layering, there will be Poisson effects, including The phenomenon of micro manufacturing cracks will occur, so that when the carbon fiber composite material is laid up, it is definitely not possible to completely lay up the layers in one direction. If this is the case, it will easily lead to the cracking of the pipe. In addition, this kind of continuous layering at the same angle will lead to low shear performance of the carbon fiber pipe, and the fracture surface is easier to delaminate, which will greatly reduce the service life of the carbon fiber pipe, especially In some harsh environments, this phenomenon is more obvious.

The carbon fiber tube manufacturer will first have a general understanding according to the performance requirements of the carbon fiber tube, and then combine the wall thickness of the tube to determine the concept of the layup design, then cut the prepreg, and then lay it up. The normal layup at the same angle will not exceed 3 layers, which can better improve the service life of the carbon fiber tube.

The Law Of The Angle Of The Layup

During the layering process, the design of the layer transition area will be carried out. The entire layer should follow the overall symmetry and uniformity, that is, the same layering method. It is necessary to complete a complete circle of the pipe surface, so that the better To ensure complete uniformity, the layers at the same angle should increase and decrease synchronously with the overall layer, and the outer layer should cover the entire surface continuously to avoid the occurrence of faults. Another point to pay attention to here is that when alternating layers, it is necessary to ensure that there is a continuous layer between every two faults, so that the overall result is more stable.

What Are The Layup Angles?

There are four common angles of carbon fiber product layup: 0°, ±45°, and 90°. A reasonable layup can improve the performance of carbon fiber products on the one hand, and on the other hand, can control the cost well.

In the process of rolling, the design of the layer should pay attention to the stress situation, and the bearing direction of the entire section should be balanced and controllable as a whole, which is very convenient during the curing process. It is evenly distributed in the order, which can reduce the interlayer shearing situation. In addition, the minimum interlayer shearing can make the stress between adjacent layers. Therefore, the adjacent layers should follow the laying angle of ±45 ° above the laying angle as much as possible. Floor.

These are the interpretations of the layup of carbon fiber tubes in roll forming.
