What is the forming process of carbon fiber tubes?
Carbon fiber tubes are a common carbon fiber product, which can be used to make the handles of suitcases, golf clubs, brackets, kite frames, etc. So how are they made? Winding is the main forming process for carbon fiber tubes. This method is simple and the products are stable. Let me explain in detail below.
Winding can be divided into hoop winding, longitudinal winding, and helical winding. In hoop winding, the mandrel rotates at a constant speed around its own axis, repeating this rotation until the surface of the mandrel tube is completely covered with yarn. The angle of rotation is around 85 degrees. In longitudinal winding, the mandrel rotates slowly around its own axis, while in helical winding, the mandrel rotates at a constant speed around its axis, and the yarn head moves intermittently back and forth along the axis of the mandrel. During this process, it is important to keep the carbon fiber stable and prevent slippage. Even a slight shake will cause positional deviation, resulting in products that do not meet the requirements. The carbon fibers must be arranged regularly, ensuring that they are adjacent but not overlapping or leaving gaps.
Choosing reasonable process parameters can improve the performance of the manufactured products. First, the content of the adhesive must be controlled, as it not only affects the thickness of the carbon fiber tube but also its strength. The curing temperature should be appropriate; a suitable temperature can improve the product's performance by 20%. In addition, the tension must also be controlled. Experiments have shown that the winding tension is related to the fatigue resistance of the carbon fiber tube.
