Temperature-resistant resin modified polyphenyl ester ternary alloy ultrasonic motor friction material

The invention discloses a ternary alloy hyperacoustic motor frictional material of the fire resistance resin modified polyphenyl ester, which solves the low friction coefficient problem, the low impact strength problem, the low abradability problem and the bad processability problem of the prior hyperacoustic motor. The invention is made by 5-25% politef, 5-20% fire resistant resin and the rest polyphenyl, which can also add one or a plurality of 10-35% fortifying fiber, 1-15% metal powder and 1-15% ceramic powder. The invention keeps all the advantages of the present polyphenyl ester plastic alloy hyperacoustic motor frictional material, which is provided with the high friction coefficient, the good abradability, the low noise, the high hardness and the high impact strength.
