The application of ptfe composite materials on trains can be roughly divided into two categories according to the load-bearing characteristics: composite non-main load-bearing parts and composite main load-bearing parts.
The non-main load-bearing parts of composite materials can be divided into main load-bearing parts (such as non-main load-bearing parts such as car bodies, floors and seats) and auxiliary parts (auxiliary components such as washrooms, toilets and water tanks), and The main load-bearing parts of composite materials mainly refer to the large load-bearing components of trains such as train bodies, cabs, and bogie frames. They are the key to replacing traditional materials with composite materials and achieving lightweight vehicles.
