A Novel Resin Based Friction Material for Al-MMC Brake Disc

A novel resin matrix friction material was specifically developed for its use against Al-MMC brake disc.Its physical and mechanical properties as well as the characteristics of friction and wear were investigated.The new friction material had excellent physical and mechanical properties and met relevant technical standard.Compared with the pad used for cast iron brake rotor,it had higher friction coefficient,lower wear rate and more stable brake torque curve.Therefore,the new friction material has great advantage over the traditional friction material for Al-MMC brake disc.The results of the 1∶1 brake tests show that the friction and wear properties of the friction couple can meet the demand for wear resistance of the brake rotors in high speed train of 200km/h.
