Carbon fiber plate is a new composite material with epoxy resin as the matrix material and carbon fiber as the reinforcing material. It is made through a special processing technology and has excellent properties such as high strength, high modulus, corrosion resistance, earthquake resistance, and impact resistance. Carbon fiber sheets are widely used in many fields.
Production process
1. Cutting of prepreg: Cut carbon fiber prepreg according to the specifications and thickness of the board. The thicker the board, the more prepreg layers are required.
2. Laying of prepreg: Layer carbon fiber prepreg on the selected metal material. Carbon fiber materials are different. During production, appropriate carbon fiber prepregs are selected according to the strength and modulus requirements of the board.
3. Curing: Put the prepreg-paved metal material into the mold, and solidify the epoxy resin through heating and pressure to form a hard carbon fiber sheet.
4. Post-processing: The cured carbon fiber plate undergoes post-processing such as cutting and polishing to achieve the required size and shape.
Processing advantages
1. Light weight: Its density is much lower than that of metal materials, and its weight is only 1/4 of steel and 20% of aluminum, which can effectively reduce the weight of components.
2. High strength and high modulus: It has high strength and modulus and can withstand large force and pressure.
3. Corrosion resistance: Epoxy resin has good corrosion resistance and can still maintain good performance in harsh environments.
4. Shock resistance and impact resistance: It has good shock resistance and impact resistance, and can withstand external impact and vibration.
5. Convenient construction: It can be made into components of various shapes and sizes through simple cutting, grinding and other processing techniques.
Processing involves cutting, grinding, drilling and other processing of cured carbon fiber sheets to meet the needs of different application fields. Cutting is to obtain the plate of the required size, polishing is to remove burrs, scratches and other defects on the surface of the plate, and drilling is to install bolts, nuts and other connectors.

Taking the aerospace fuselage tail compartment side skin as an example, its advantages are obvious, such as:
1. Lightweight and high strength: It has extremely high specific strength and specific stiffness. Its density is only 1/4 of steel, but it can provide similar or even higher strength and stiffness than steel. In aircraft design, the use of carbon fiber materials can significantly reduce structural weight, improve fuel efficiency, and increase load capacity.
2. Corrosion resistance: Carbon fiber itself is a material with excellent chemical stability. Its surface is not prone to chemical reactions, so it has good corrosion resistance. In the application of the aircraft tail cabin side skin, it can resist the corrosive effects caused by environmental factors (such as heat and humidity, salt spray, etc.) and extend the service life.
3. Excellent fatigue performance: It has high fatigue strength and can maintain a long service life under repeated stress. This is crucial for vehicles such as aircraft that require frequent takeoffs and landings, as it can reduce maintenance times and improve operating efficiency.
4. Shock absorption performance: Although the elastic modulus of carbon fiber is higher than that of metal, its damping performance is better and can absorb and reduce vibration. This makes the aircraft more stable during flight, reducing fatigue for pilots and passengers, while also reducing stress on the structure.
5. Small thermal expansion coefficient: The thermal expansion coefficient of carbon fiber is very small, close to zero, which means that its dimensional stability is very good when the temperature changes. This is critical for the aircraft to maintain structural accuracy in extreme temperatures.
6. Smooth surface: It has a smooth surface, which helps reduce air resistance and improve flight efficiency. At the same time, in the application of the tail cabin side skin, the smooth surface is also conducive to reducing the reflectivity of radar waves and has a certain stealth effect.
7. Processing performance: Advanced carbon fiber composite material processing technology can realize the manufacturing of complex shapes, which provides greater freedom in the design of the aircraft tail cabin side skin and can meet diverse design needs.
8. Environmental adaptability: It can adapt to a variety of environmental conditions, including high temperature, high cold, and high humidity environments. Its performance is stable and not easily affected by the environment.
9. Economy: Although the price of carbon fiber materials is relatively high, its cost is gradually decreasing with the advancement of production technology and expansion of scale. At the same time, due to its durability and low maintenance costs, carbon fiber materials are becoming more and more economical in the long run.
10. Sustainability: Carbon fiber materials consume low energy during the production process and are recyclable, meeting the requirements of sustainable development.
In summary, it has obvious comprehensive advantages in the application of aircraft tail cabin side skins, and can meet the needs of modern aircraft for lightness, high strength, durability, economy, and environmental protection. With the continuous advancement of material processing technology, its application in the aerospace field will become more extensive.
In short, carbon fiber sheets, as a new type of composite material, have excellent properties such as light weight, high strength, high modulus, corrosion resistance, earthquake resistance, and impact resistance. It has been widely used in many fields and has broad market prospects in the future.
