The main advantages of carbon fiber tubes

1. Good mechanical properties: Carbon fiber has excellent mechanical properties. For example, the density of T300 carbon fiber tube is only about 1.6g/cm, and the tensile strength can reach 3600Pa. It can be seen that carbon fiber tube has a very high lightweight advantage and outstanding mechanical properties. In addition, carbon fiber pipes also have high fatigue resistance. Compared with pipes made of other materials, carbon fiber pipes are light in weight and have higher performance advantages.

2. Good chemical properties, carbon fiber pipes have very good chemical stability, carbon fiber pipes still maintain good stability in the environment of acid, alkali and salt corrosion, and have very high corrosion resistance, which also makes carbon fiber pipes It can be used very well in many fields.

3. Good thermal stability. Carbon fiber can still have good stability despite temperature differences. The linear expansion coefficient of thermal expansion and contraction is also relatively low and will not creep easily, which can better ensure the accuracy of the tube.

4. The advantages of shock absorption are very obvious. In carbon fiber products, because each carbon fiber is evenly distributed inside of CFRP product, this results better overall structural stability of the carbon fiber, so that the vibration can be well absorbed under pressure. It is dispersed and has a good shock absorption effect. Compared with steel, this is also a good advantage.

In addition, it has the advantages of long life, conductivity, small thermal expansion coefficient, high specific modulus, fatigue resistance, creep resistance, and high temperature resistance. The disadvantage is that it is conductive (Ωcm - 1.5×10-3) and is not wear-resistant.

For carbon fiber tubes used in different occasions and environments, there are also different requirements for its lamination design. Because carbon fiber prepregs or carbon fiber filaments has different specifications and properties , designers need to focus on the specific strength requirements of carbon fiber tubes. They can strengthen the lamination on needed area or points by designing to achieve the best results. For example, the Carbon fiber bicycle pipe fittings, aircraft model pipe fittings, paddle pipe fittings, sailboat masts, golf clubs, etc. have different stress characteristics, which requires experienced designers to design desired products based on actual needs.

Due to the above performance advantages, carbon fiber tubes have a wide range of applications, such as in aircraft, automobiles and other industries that require high lightweight. At the same time, due to their small creep, they can also be used in robotic arms, space telescope tubes, rollers, etc. Shaft production.
