| Title | CARBON BASED SINTERED CONTACT STRIP MATERIAL HAVING WEAR RESISTANCE |
| Abstract |
PROBLEM TO BE SOLVED: To provide a carbon based sintered contact strip material which has wear resistance, and is fitted to the pantograph of an electric vehicle. SOLUTION: The carbon based sintered contact strip material having wear resistance is formed of a carbon-copper composite material obtained by mixing carbon powder and copper powder, and compacting and firing the mixture. The d (002) face spacing in carbon by an X-ray diffraction method is 0.35 to 0.345 nm. |
