Traditional structural materials mostly use steel, aluminum, stainless steel, aluminum alloy, etc. as the main materials. With the increasing demand for lightweight equipment and structural parts, carbon fiber composite materials have begun to gradually replace traditional structural materials. With carbon fiber composite materials With the rapid development and wide application, the current application and amount of carbon fiber in the key parts of the equipment has gradually become one of the indicators to measure the advanced structure of the equipment.
1. Lightweight
The density of lightweight aluminum alloy is 2.8g/cm³, while the density of carbon fiber composite is about 1.5, which is only half of that. However, the tensile strength of carbon fiber composite can reach 1.5GPa, which is more than three times higher than that of aluminum alloy. This advantage of low density and high strength makes the application of carbon fiber composite materials in structural parts 20-30% less than the same performance material, and the weight can be reduced by 20-40%.
2. Versatility
After years of development, carbon fiber composite materials have combined many excellent physical properties, mechanical properties, biological properties and chemical properties, such as heat resistance, flame retardancy, shielding properties, wave absorption properties, semiconducting properties, superconducting properties, etc., Moreover, the composition of different advanced composite materials is different, and there are certain differences in their functionality. Comprehensiveness and multifunctionality have become one of the inevitable trends in the development of carbon fiber composite materials.
3. Maximize economic benefits
The application of carbon fiber composite materials in equipment can reduce the number of product components. Since the connection of complex parts does not require riveting and welding, the demand for connected parts is reduced, which effectively reduces the cost of assembly materials, assembly and connection time, and further reduces costs.
4. Structural integrity
Carbon fiber composites can be processed into monolithic parts, that is, several metal parts can be replaced by carbon fiber composite parts. Some parts with special contours and complex surfaces are less feasible to be made of metal, and the use of carbon fiber composite materials can well meet actual needs.
5. Designability
Using resin and carbon fiber composite structure, composite materials with different shapes and properties can be obtained. For example, by selecting appropriate materials and lay-up procedures, carbon fiber composite products with zero expansion coefficient can be processed, and the dimensional stability of carbon fiber composite materials Superior to traditional metal materials.
