Introduction to Carbon Fiber Products
Although we have displayed some civilian products on our website, in fact, most of the products manufactured by our company are used in military products. Due to confidentiality reasons, it is not convenient for us to release photos. Our products can be found on Chinese warships, drones, and missiles. In this regard, we generally do not engage in design work. Usually, customers provide the drawings and performance requirements, and we turn the customers' designs into tangible products.China currently has a very complete carbon fiber industrial chain, and it can produce carbon fibers ranging from T300, T700, T800 to T1100. The following is some general information:
Carbon fiber products are high-performance products made by compounding carbon fibers as the main reinforcing materials with matrix materials such as resins. The following is an introduction:
Raw Materials and Production Processes
Raw Materials: The main raw material is carbon fiber, which is made from polyacrylonitrile (PAN) fibers, pitch fibers, etc. through high-temperature treatment processes such as pre-oxidation, carbonization, and graphitization. It has the characteristics of high strength and high modulus. The commonly used matrix material is epoxy resin, which has good adhesion, corrosion resistance, and mechanical properties.
Production Processes: The common ones include the compression molding process. The carbon fiber prepreg is cut and then placed in a mold, and it is cured and formed under a certain temperature and pressure. This process is suitable for manufacturing products with regular shapes and high precision requirements. There is also the filament winding process. The carbon fiber bundles are impregnated with resin through a resin tank and then wound around a mandrel according to a certain pattern. After curing and demoulding, the product is obtained. This process is often used for manufacturing pressure vessels, pipelines, etc. In addition, the hand lay-up process involves laying carbon fiber cloth layer by layer on the surface of the mold and brushing resin, and then curing and forming. This method is suitable for the production of small-batch and large-sized products.
Performance Characteristics
High Strength and High Modulus:The strength of carbon fiber products is much higher than that of steel, and the modulus is also much higher than that of general metal materials and plastics. For example, the tensile strength of some carbon fiber composites used in aerospace can reach more than 3000MPa.
Lightweight: Its density is only about one-fourth of that of steel. Under the premise of ensuring structural strength, it can greatly reduce the weight of products, which is of great significance to the aerospace, automotive and other fields.
Good Corrosion Resistance: The carbon fiber and the epoxy resin matrix endow it with good resistance to chemical substances such as acids, alkalis, and salts. It can be used to manufacture components used in harsh environments, such as structural components in marine engineering equipment.
Excellent Fatigue Resistance:Compared with metal materials, carbon fiber products have higher fatigue resistance when subjected to repeated loads, and can maintain stable performance for a long time, reducing maintenance and replacement costs.
Application Areas
Aerospace Field:It is used to manufacture structural components such as aircraft wings, fuselages, and tail wings, as well as the shells and supports of satellites. It can effectively reduce the weight of aircraft and improve fuel efficiency and flight performance.
Automotive Industry Field: It is applied to components such as automotive bodies, chassis, engine hoods, and wheels. It can not only reduce the weight of cars, achieve energy conservation and emission reduction, but also improve the handling performance and collision safety of cars.
Sports Goods Field: Common examples include bicycles, badminton rackets, tennis rackets, golf clubs, etc. By taking advantage of the high strength, lightweight, and good elasticity of carbon fiber products, the performance and user experience of sports goods can be improved.
Energy Field: For example, in the blades of wind turbines, carbon fiber products can meet the requirements of large size, lightweight, and high strength of the blades, improving the efficiency of wind power generation. It can also be used to manufacture the supports of solar panels and other components.
Development Trends
With the continuous progress of technology, carbon fiber products are developing towards higher performance and lower cost. On the one hand, new carbon fiber production technologies and high-performance resin matrices are being developed to further enhance the performance of carbon fiber products. On the other hand, by optimizing production processes and expanding production scale, the production cost of carbon fiber products can be reduced, enabling them to be widely applied in more fields.
