Tribological Performance Comparison and Analysis on Friction Material: Four Modified Phenolic (PF) Resins

Abstract:

This paper makes PF weaving friction material (p0.0) from tung oil, PF weaving friction material (BP) from boric acid, modified PF weaving friction material (SP) of nanopalygorskite by in-situ method, and modified PF weaving friction material (MP) of nanopalygorskite by blending method. The contrast tests of frictional properties are carried out on DMS-1 friction-abrasion tester. Hot recession test is performed on CHASE-M600 testing machine, and surface appearance analysis of friction sample is made on electronic probe. The result shows that after modification, the heat resistance and thermal stability of PF are all improved to different extent. SP friction material has best thermal stability and strongest braking ability under high temperature; while BP takes second place, and P0.0 is the worst. The heat resistance of BP, SP and MP is stronger than P0.0. The critical temperature of hot recession for weaving friction material on the base of nanopalygorskite/tung oil PF raises by 40~50°C. On the aspect of frictional properties, friction coefficients of SP, BP, and MP show quite stable. Among these samples, SP has the most stable friction coefficient, and P0.0 the worst. The wear rate of SP, BP and MP has the same trend with the temperature changes. However, the wear rate of P0.0 is getting intense with temperature rise. Its wear rate is much higher than SP, BP, and MP’s under same temperature.
