Abstract
A friction material was developed after studying carbon fiber and melamine modified phenolic resin, which was made by thermo-compression craft. Thermal stress coupled field of friction material is analyzed by ABAQUS finite element software, the physical mechanical and friction and wear performance were investigated, the worn surfaces wear mechanism of friction materials were observed by Scanning Electron Microscope (SEM)and x-ray diffractometer, and comparison with ordinary phenolic resin friction material. It is shown that the friction and wear performance can be improved for friction material using both carbon fiber and melamine modified phenolic resin at the condition of high temperature, and the thermal decomposition and thermal fading of friction material were reduced in braking process. The mechanical properties and friction and wear properties of friction materials of melamine modified resin are improved compared with the friction materials of phenolic resin brake pads. It is thermal abrasion at high temperature due to phenolic resin decomposition accompanying with abrasive wear and fatigue abrasion, the wear mechanism of friction materials of melamine modified phenolic resin brake pad is fatigue abrasion.
