As the basic product of carbon fiber composite materials, carbon fiber tube need to be connected with other structural parts in actual use, and it is more common to connect with metal parts. The following methods are often used when connecting with metal parts. Boshi carbon fiber is here to give you a relevant explanation.
1. Adhesive connection. Adhesive connection is the most commonly used connection method. It mainly uses high-strength viscous glue to connect the carbon fiber tube with the parts. Before connecting, it is necessary to clean the surface of the pipe with chemicals without impurities, or roughen the surface of the place to be connected to increase the ability of adhesion, and then use glue to connect. This connection method has the functions of anti-fatigue, vibration reduction, and anti-corrosion, and is the most widely used method by many carbon fiber product manufacturers at this stage.
2. Mechanical connection, the bonding strength of the mechanically connected carbon fiber tube is higher than that of the adhesive connection, and it is generally used in places where the bearing capacity is large or where disassembly and maintenance are often required. In the mechanical connection, there are more threaded connections and rivet connections. In the actual experiment, the large load can be better transmitted, but the addition of metal connectors will cause the product gravity to increase.
3. Pre-embedded connection, pre-embedded connection is also a very common connection method. Boshi is generally used in the production of robotic arms. During the carbon fiber tube laying stage, the metal parts are pre-embedded in the designated position, and then followed by the mold. Pressurized high temperature curing, become a whole process. This type of connection requires products with low pipe tolerances, especially when using mixed layups of different prepregs.
4. Hybrid connection, hybrid connection, is to connect together through mechanical connection and glue to make the connection effect better. This kind of connection is usually applied to products that have higher requirements for stress and load-bearing.
The above are the four commonly used methods for connecting carbon fiber tubes and metal parts. As for which connection method to use, it depends more on the specific product to decide.
