Deals with a novel conductive friction material, metal fiber reinforced moulded impermeable graphite (MFRMIG). The new material owns excellent properties with bending strength: 82?MPa; compression strength: 138?MPa and the volume resistivity: 25?μΩm. The relationship between the volume resistivity of MFRMIG and conductive filler volume fraction (the ratio ofmetal of fiber to graphite powder) and the effect of filler volume fraction on the transverse strength of MFRMIG were studied. Both the mechanical strength of the material and the results of real tests on trolley bus show that MFRMIG is an excellent conductive friction material candidate.
