The application research of composite materials in aluminum forgings of construction machinery is mainly to explore the application of composite materials in aluminum forgings to improve the performance and function of products. Composite materials are composed of two or more kinds of materials, which have excellent comprehensive properties and diversified application potential. In the field of construction machinery, the use of composite materials can provide the following advantages:
- Lightweight: composite materials have lower density and higher strength, compared with traditional metal materials, the use of composite materials can effectively reduce the weight of the product, improve the carrying capacity and fuel economy of the whole machine.
- Strength and stiffness improvement: The mechanical properties of composite materials can be regulated by selecting different fiber reinforced materials and resin matrix materials. Fiber reinforcement materials, such as carbon fiber and glass fiber, can be added to aluminum forgings to significantly improve their strength and stiffness, and increase their seismic, torsional and fatigue resistance.
- Improved wear resistance and corrosion resistance: the composite material has good wear resistance and corrosion resistance, which can reduce the size loss and surface corrosion of mechanical parts, extend the service life, and reduce maintenance costs.
- Increased freedom of design: The molding methods of composite materials are diverse, and can be flexibly designed according to the needs of products through injection molding, lamination, textile, layout and other processes. It can meet the needs of construction machinery aluminum forgings in structural design, shape curve, component integration, etc., and improve the overall performance of the product.
- Enhanced energy absorption capacity: the composite material has good energy absorption characteristics, which can be used to improve the safety and stability of construction machinery in harsh environments such as shock and vibration.
Therefore, the application research of composite materials for aluminum forgings of construction machinery is of great significance for improving product performance, reducing energy consumption and optimizing structural design. In practical applications, it is necessary to conduct in-depth research on different composite materials and processes, and select suitable composite material types and processing technologies to ensure the reliability and economy of products. At the same time, it is also necessary to pay attention to the interface bonding strength, heat resistance, corrosion resistance and other issues of composite materials and aluminum forgings to ensure the stable application of composite materials in the field of construction machinery.
