Diamond composite materials Play an Important Role in the Aerospace Field

Diamond composite materials, with a thermal conductivity as high as approximately 1000 W/(m·K) and an extremely low coefficient of thermal expansion, is an excellent material. Copper alloys, on the other hand, exhibit good electrical and thermal conductivity and are widely used in industry. When diamond powder and copper alloy are combined through an appropriate process to form a metallurgical bonding interface between diamond particles and copper alloy, diamond-copper composites with excellent thermal conductivity and a suitable coefficient of thermal expansion are created.

This unique combination of properties endows diamond-copper composites with irreplaceable advantages in many fields. In the aerospace field, where extremely high requirements are imposed on material performance, diamond-copper composites can not only withstand the test of extreme environments but also meet special thermal management needs.

In the aerospace sector, diamond-copper composites also play a crucial role. Aerospace engines, satellite electronic devices, and other components generate a large amount of heat during operation; moreover, aerospace equipment has extremely strict requirements on material weight, performance, and other aspects. Diamond-copper composites not only have high thermal conductivity but also feature low density and high strength, enabling them to meet the heat dissipation needs of aerospace equipment under extreme environments such as high temperature, high pressure, and high radiation. For instance, when diamond-copper composites are used as heat dissipation materials for electronic devices on satellites, they can not only reduce the weight of the satellite but also ensure the stable operation of the devices in the space environment.

From the perspective of application trends, with the continuous advancement of science and technology, the performance requirements for diamond-copper composites are becoming increasingly higher. In the future, diamond-copper composites have broad application prospects in fields such as new energy power generation, high-power optoelectronic devices, power electronics, and IGBTs. Taking new energy power generation as an example, equipment such as wind turbines and solar panels generate heat during operation, which affects power generation efficiency and equipment service life. The application of diamond-copper composites is expected to solve these heat dissipation problems and improve the stability and efficiency of new energy power generation.
