1. Gluing: Gluing is the most basic way to connect carbon fiber components and metal components, which is to add suitable structural glue between the two to fix them. Before gluing, some preparatory work needs to be done. The joints between the carbon fiber components and the metal components are cleaned to remove surface impurities, and then polished to improve the surface roughness and make the bonding more stable.
2. Mechanical connection: Mechanical connection is a common way of connecting metal materials, such as threaded connection and rivet connection. This method can transmit greater load, has better peel resistance, and can be repeatedly disassembled, but it will increase the overall weight of the component. For connecting carbon fiber and metal, this method is difficult to operate. First of all, the rigidity of carbon fiber is large and it is troublesome to process. In addition, the tapping of carbon fiber components is difficult, which is not an ideal connection method.
3. Hybrid connection: Reasonable application of two processes, mechanical connection and glue connection, effectively improves the tightness of the connection and reduces the difficulty of operation. It is currently the most used method.
4. Pre-embedded: In some cases, the connection between carbon fiber and metal cannot achieve the desired effect. At this time, pre-embedded treatment can also be carried out. In the process of making carbon fiber components, the metal parts are put into the carbon fiber prepreg to make the two into a whole. This connection method is more effective, but it is also more difficult and the investment cost is higher.
The above 4 methods basically cover all the bonding paths between carbon fiber tube and metal. In the actual processing, the bonding is the simplest, the mechanical connection requires opening and tapping, and the pre-embedding requires a more complex mold. Therefore, the connection is If the strength requirement is not high, the glue connection is sufficient.
