Carbon fiber tube is widely used in aviation, aerospace, automobile, machinery, construction, sports equipment and other fields of structural parts or functional parts. It is characterized by light weight, high strength, strong stiffness and wear resistance, corrosion resistance and other properties, is an excellent structural material. This paper analyzes the production mode of carbon fiber tube raw materials, production process, application and future development prospect of carbon fiber tube.
The raw materials of carbon fiber tubes are mainly synthetic resins such as polyimide or polypropylene and carbon fiber. The production process mainly includes the following processes:
1. Determine the material and performance requirements of carbon fiber.
2. Select and soften the corresponding carbon fiber material to make it more suitable for manufacturing carbon fiber tubes.
3. According to the diameter, length and application requirements of the pipe, the use of composite material processing technology, the polymer composite materials such as polyimide or polypropylene are coated on the surface of carbon fiber, and then heated and dried to make carbon fiber prepreg stick.
4. Place these prepreg sticks into the mold to form a preformed module that matches the shape and size of the desired product.
5. High temperature and high pressure treatment is carried out in the sinter to form a fixed array of chips and fibers, and finally achieve the required product performance indicators.
The production process of carbon fiber tube includes design, selection, processing, tube body forming, thermal curing and other processes, including the following stages:
1. Design and selection stage: determine the structure and specifications of carbon fiber tubes, as well as the number of required manufacturing. And the selection of carbon fiber, according to the demand to choose different types, different specifications of carbon fiber materials.
2. Processing stage: carbon fiber is processed so that it can be formed into prefabricated parts.
3. Tube body forming stage: the prefabricated parts are sent into the steel mold, and then the air is sucked out by vacuum, and the carbon fiber structure is formed by high temperature heat-curing adhesive.
4. Surface treatment stage: according to product requirements, the pipe surface is treated in various ways, such as grinding, spraying and so on.
5. Testing stage: Test the carbon fiber tube made, including physical, chemical and other aspects of testing, to ensure product quality.
