Carbon fiber composite materials have unique advantages such as low thermal expansion coefficient, good structural dimensional stability, high specific strength and stiffness, strong designability, good fatigue fracture resistance, corrosion resistance, easy overall molding, and excellent mechanical properties. It has played an important role in aviation, aerospace, and civil industries. So, what aspects generally control the quality of carbon fiber tubes?
1. Different raw materials
In the entire production and processing of carbon fiber tubes, the different raw materials will have a significant impact on the performance of the final carbon fiber tube. Many people will try to choose imported carbon fiber materials when selecting raw materials. The reason is that China's carbon fiber industry has developed slowly in the past, and the performance of raw materials is not as good as that of carbon fiber in the United States and Japan, so the performance of the carbon fiber products made will be worse. With the continuous improvement of domestic technology, the carbon fiber raw materials in China are not much different from those imported from abroad, and the performance of the carbon fiber pipes produced will not differ much. The performance of products varies depending on the material model. The performance of carbon fiber pipes produced from carbon fiber T300 raw materials and carbon fiber T800 raw materials is definitely different. Therefore, the different raw materials will directly affect the performance of carbon fiber pipes.
2. Mold design
In the production of carbon fiber pipes, molds are used for all specifications of pipes. Generally, round pipes are more commonly molded using core molds, while square and rectangular pipes are molded using compression molding. Different molds need to be made here. Try to choose materials such as steel and hard aluminum when making molds. If Moxian uses materials such as wood and fiberglass, problems will arise during high-temperature curing. Steel molds can be used for a long period of time. If hard aluminum molds are used, the coefficient of thermal expansion is higher, and curing internal pressure will be generated in high temperature environments, resulting in higher performance of carbon fiber pipes produced.
3. Process selection
In the production of carbon fiber tubes, there are program methods such as extrusion, winding, rolling, and molding. However, the performance of carbon fiber tubes produced under different processes is different. For example, winding process can better design the layout of carbon fibers and obtain better carbon fiber strength. The rolled carbon fiber tube can be mechanically automated. Then it must be that the performance of carbon fiber tubes formed by winding is better than those formed by rolling, and even better than those formed by extrusion.
4. Layer design
If the layer design of carbon fiber pipes formed by rolling is different, the performance of the carbon fiber pipes will also be different. For example, if the required carbon fiber pipes move laterally, a 45 ° layer can improve the torque resistance of the pipes. When laying in the 90 direction, the resistance of the pipes can be higher. Our company will carry out corresponding layer design for the actual application of carbon fiber pipes.
