Carbon fiber is known as a new inorganic material. It has a series of excellent properties, such as high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance, radiation resistance, conductivity, heat transfer, shock absorption, noise reduction and so on. As a typical high performance fiber, carbon fiber is widely used as a reinforcing fiber of advanced resin matrix composites. At present, its application field is mainly in Aeronautics and aeronautics, mainly because it can greatly reduce the weight of structural prefabrication and further improve the technical performance.

There are a large number of X, gamma rays and neutrons in the radiation field environment of nuclear power plants and nuclear power plants. In order to ensure absolute safety, these X, gamma rays and neutrons need high-density radiation shielding materials. At present, the commonly used materials are lead-boron polyethylene, boron-containing polypropylene, cadmium plate, boron steel, tungsten-based heavy alloy, boron carbide and aluminium-based boron carbide. The above materials are only lead-boron polyethylene. Material can shield x, gamma rays and neutrons at the same time. Other materials can only shield one of the x, gamma rays or neutrons.

High Cobalt-Tungsten Carbide Powder for Explosive Spraying in Jet Fighter Engine

High Cobalt-Tungsten Carbide Powder Image

In the field of aero-engines in China, tungsten carbide has good impact resistance, toughness and bond with the substrate, and has high density. It has been used as a fan blade damping boss and compressor blade damping boss on the aero engine. Crown blade canopy damping surface and turbine blade canopy damping surface have been successfully applied. For example, the Russian-made AF-31 series engine equipped with Su-27, J-10, J-11 or China's WS Series engine.
