Carbon fiber is a new type of material with light weight and high strength, which has a broad application prospect. Carbon fiber rod It is a rod material made of carbon fiber, widely used in aerospace, automotive industry, sporting goods, construction engineering and other fields. This paper will introduce the carbon fiber manufacturing process and application research in detail.

1. Carbon fiber manufacturing process

The key process of carbon fiber manufacturing includes the preparation of fiber raw materials, spinning, high-temperature carbonization and heat treatment. First, the raw materials for carbon fiber manufacturing are chemically treated to remove impurities and enhance the crystallinity of the fiber. Next, the treated fiber raw material is spun through a spinning machine to form a continuous fiber bundle.

After spinning, the fiber bundle is sent to the high-temperature carbonization furnace for carbonization process. At high temperature (usually 1000-3000 ° C), the non carbon elements in the fiber raw materials can be removed, and the fiber structure changes to form carbon fibers with highly crystallized fibers. Finally, after heat treatment, the carbon fiber is strengthened to improve its strength and rigidity, and the final carbon fiber rod is made.

2. Application research of carbon fiber rod

Carbon fiber rod has been widely used in various fields due to its light weight and high strength. The following will be introduced from four aspects: aerospace, automotive industry, sporting goods and construction engineering.

2.1 Aerospace field

The application of carbon fiber rods in the aerospace field is mainly reflected in aircraft, rockets, satellites and other components. Because of its light weight and high strength, carbon fiber rods can reduce the weight of aircraft, improve fuel utilization, and increase the rigidity and stability of its structure.

2.2 Automobile industry

Carbon fiber rod is mainly used in automobile body structure, chassis and suspension system. The use of carbon fiber rod can reduce the overall weight of the car, improve fuel efficiency, and at the same time increase the impact resistance and stability of the car, improving the driving experience.

2.3 Sporting goods

Carbon fiber sticks are widely used in the field of sports goods, such as ski poles, golf clubs and bicycle frames. Because carbon fiber rod has the characteristics of light weight, high strength and corrosion resistance, sporting goods made of carbon fiber can improve the competitive level of athletes and reduce the burden of equipment.

2.4 Construction works

The application of CFRP in construction projects is mainly reflected in concrete reinforcement, beam column reinforcement and bridge construction. As a kind of lightweight and high-strength material, carbon fiber rod can effectively strengthen and strengthen the structure of buildings, improve their seismic performance and service life.

3. Summary

Through the detailed introduction of the manufacturing process and application research of carbon fiber bar, it can be seen that carbon fiber bar, as a kind of material with high strength and light weight, has broad application prospects. In the future, with the continuous improvement of manufacturing process and technological breakthrough, carbon fiber bars will be applied in more fields, promoting scientific and technological progress and social development.
