FRICTION MATERIAL AND MANUFACTURING METHOD OF THE SAME

摘要

A manufacturing method of friction materials is provided to manufacture friction materials having excellent high temperature strength, abrasion resistance and friction coefficient. The manufacturing method of friction materials comprises the steps of: preparing mixed powder of 7~25 weight percent iron powder, 4~15 weight percent silica powder, 5~30 weight percent graphite powder, 0.5~5 weight percent carbon nano-tube, and 58~76 weight percent copper-nickel alloys(S100); immersing the prepared mixed powder in a mixing solution containing coatings and a solvent(S200); volatilizing the solvent and mixing the mixed powder(S300); manufacturing a molded body by inputting the mixed powder in a mold applied with zinc stearate as a lubricant and applying a single pressure type vertical pressure of 4~8 ton/cm^2(S400); and completing friction materials by sintering the molded body at 850~925‹C for 1~3 hours(S500).
