A LOW-STEEL TYPE FRICTION MATERIAL AND A BRAKE FOR VEHICLE COMPRISING THE LOW-STEEL TYPE FRICTION MATERIAL

摘要

PURPOSE: A low-steel friction material and a vehicle brake including the same are provided to improve frictional characteristic due to the change of frictional coefficient according to speed and braking deceleration and due to an excellent resistance to a fade. CONSTITUTION: A low-steel friction material comprises: a solid lubricant whose grain size is 180-220 micron; and an abrasive material whose grain size is 0.5-10 micron. The solid lubricant includes graphite, antimonous sulphide, zinc sulfide, copper sulfide, or the mixture of the same. The abrasive includes zirconium silicate, alumina, silicon dioxide, magnesium oxide, or the mixture of the same. The volume percentage of the solid lubricant is 13-15%. The volume percentage of the abrasive is 4-6%. The friction material includes textile material, binder, filler, and friction modifier.
