Effect of Nano Sodium Titanate Whisker and Aramid Pulp on the Friction and Wear Behavior of Resin-Based Brake Material

Abstract:

The dependence of friction and wear behavior on nanosodium titanate whisker and aramid pulp in a designed resin-based brake material was systematically analyzed. Higher contents of aramid pulp enhanced the hardness of the brake materials. In addition, the maximum impact energy of the material reached 0.392 J/cm² where the ratio of aramid pulp to sodium titanate whisker is 0.75. At same time, the friction coefficient was stable between 0.38 and 0.45, and the wear rate was 5%. The samples with higher contents of nanosodium titanate whiskers and aramid pulp showed more uniform furrows, fewer delaminated craters, more moderate layers transfer and more stable contact plateaus.
