Research on Anti-static Technology and Standard of Carbon Fiber Composite for High-speed Railway

With the increasing demand for thermoplastic carbon fiber composite materials for rail transit,the project for demonstration of key technologies and applications of CFRP reinforced thermoplastic composite materials focusing on orbital interchanges was approved in 2018.The project is to break through the key technologies such as material design and optimization of thermoplastic carbon fiber composites,component structure design,and key processes of rapid prototyping equipment to achieve efficient mass manufacturing and typical application verification of thermoplastic carbon fiber composite parts in rail transit and other fields.In the high-speed state,friction between the surface of the car body and dry air creates good conditions for the generation of static electricity.Friction will increase charge accumulation.When the electrostatic potential of the car body reaches several thousand volts,it will bring great harm to the crew.So the research on carbon fiber composite anti-static technology and its standards is of great significance in ensuring the safety of driving,personal safety and driving comfort.
