A composite material is a multiphase material composed of two or more materials with different properties through physical or chemical methods. These materials can each maintain their original properties and work together to meet the requirements of use. Composite materials are usually used in many fields due to their excellent properties such as high performance, light weight, corrosion resistance, and fatigue resistance.
According to different classification methods, composite materials can be divided into the following categories:
1.According to the different substrates in composite materials, they can be divided into resin matrix composites, metal matrix composites, ceramic matrix composites and cement-based composites.
2.According to the composition of composite materials, it can be divided into heterogeneous composites and homogeneous composites. Heterogeneous composites are made up of materials with different properties, while homogeneous composites are made up of the same material.
3.According to the mechanical properties of composite materials, they can be divided into structural composite materials and functional composite materials. Structural composites are mainly used to bear loads and transfer energy, while functional composites are mainly used to achieve specific functions, such as conducting, emitting light, generating heat, etc.
Composite materials are used in a wide range of applications, including aerospace, automotive, construction, sports equipment, medical equipment, electronic appliances, etc. For example, in the aerospace sector, composite materials are used to make structural and functional parts for aircraft and satellites;In the automotive sector, composite materials are used to make body, frame, and engine components;In the construction sector, composite materials are used in the manufacture of bridges, houses, and building components;In the field of sports equipment, composite materials are used in the manufacture of golf clubs, bicycle racks and skateboards, among othersIn the field of medical devices, composite materials are used in the manufacture of artificial joints, dental implants, and drug carriersIn the electrical and electronics sector, composite materials are used in the manufacture of circuit boards, batteries, sensors, etc.
In conclusion, composite materials are an advanced material with a wide range of application prospects, and their properties and application fields are constantly expanding and innovating. With the continuous progress of science and technology and the continuous improvement of application needs, the research and development and application of composite materials will be more in-depth and extensive.
