Pantograph pan composite material for high-speed electric multiple units and preparation method of pantograph pan composite material
The invention discloses a preparation method of a pantograph pan composite material for high-speed electric multiple units. The preparation method comprises the following steps: proportionally weighing raw materials: 30-60 percent of chopped carbon fiber, 20-30 percent of phenolic resin powder, 10-20 percent of pitch coke powder, 10-20 percent of crystalline graphite powder, and 1-10 percent of copper powder, uniformly mixing the weighed raw materials, pouring the mixture into a moulding press die for compression moulding, successively placing a green body into a muffle furnace for pre-oxidation, a carburization furnace for carburization, an isothermal chemical vapor deposition furnace for densification, and a high-temperature graphitization furnace for graphitization, and obtaining the pantograph pan composite material. The pantograph pan composite material is processed to obtain a carbon-carbon composite material pantograph pan. The carbon-carbon composite material pantograph pan, which is prepared according to the preparation method, is not only short in cycle and low in cost, but also excellent in various performance indexes, can supply stable and safe electric power for the high-speed electric multiple units, and ensures the efficient operation of a locomotive.
