The Carbon Fiber Connection Methods

Carbon fiber composite materials are usually used in the manufacture of automobiles, rail vehicles and various mechanical equipment in the form of parts. Glue connection. Different connection methods have their own advantages and disadvantages. Let’s take a look at them together in this article.  

For components whose thickness, length or overall volume account for a large proportion of the entire equipment, mechanical connection is usually used, because heavier or larger mechanical equipment tends to generate greater vibration and friction during operation.

The mechanical connection is more conducive to the transmission of larger concentrated loads, and this method is more reliable. Moreover, if the parts need to be disassembled and replaced, it is more convenient to use a mechanical connection.Carbon fiber material, as a high-performance, lightweight, high-strength composite material, has been widely used in aerospace, automobiles, sports equipment and other fields.

In the micro manufacturing and use of carbon fiber materials, the selection and use of connection methods are crucial.This article will introduce in detail the different connection methods of carbon fiber materials, and analyze their advantages, disadvantages and usage scenarios.

Mechanical Connection

Mechanical joining is a type of joining that mechanically joins carbon fiber materials together. Common mechanical connection methods include bolt connection, rivet connection, etc. The advantages of this connection method are high connection strength and good stability, and it is suitable for occasions that need to bear larger loads. However, mechanical connections require precise processing and installation, are costly, and may cause damage to carbon fiber materials.

Welding Connection

Welding is a method of connecting by heating the surface of carbon fiber materials to cause a chemical reaction. The advantages of this connection method are high connection strength and good stability, and it is suitable for occasions that need to bear larger loads. However, welding connections require the use of professional welding equipment and skills, which is difficult to operate and may cause damage to carbon fiber materials.

Adhesive Connection

Adhesive joining is a type of joining that uses adhesive to join carbon fiber materials together. Common adhesives include epoxy resin, polyurethane, etc. The advantages of this connection method are simple operation and low cost, and it is suitable for occasions that require quick assembly. However, the strength and stability of adhesive connections are relatively low and may cause some damage to carbon fiber materials.

Conclusion

This article introduces in detail the three different connection methods of carbon fiber materials: mechanical connection, welding connection and adhesive connection, and analyzes their respective advantages, disadvantages and usage scenarios. In actual applications, appropriate connection methods should be selected according to specific needs and scenarios to ensure the safety and reliability of carbon fiber materials.

For components with light weight and small volume machining, they can be connected by gluing, because compared with mechanical connection, gluing is not only easy to obtain a smooth transition shape that meets the requirements of aerodynamics, but more importantly, it will not significantly increase the size of the body. Self-weight, and self-weight has a great influence on small, especially precision equipment, but because the bonding strength changes with environmental changes such as temperature and humidity, the reliability is reduced compared to mechanical connections. Not suitable for parts with high strength requirements.

We are also able to handle larger production runs and provide a competitive pricing. If we don’t have the material or finish you require, we are more the willing to look at bringing it in for you.

What Is Carbon Fiber?Carbon fiber is made of polyacrylonitrile (PAN) (or pitch, viscose) and other organic fibers by carbonization (removal of most elements except carbon) by pyrolysis method under inert gas at high temperature above 1,000 °C. Inorganic polymer fibers with a carbon content of more than 90%.
