Abstract:To get a friction material formula with good brake performance and low noise, the friction material adopting low resin content was designed, and the formula was optimized,through orthogonal experimental design. The friction and wear property and mechanical property of the friction material were tested by constant speed friction test machine and compression feature testing machine. The influence of different component in the formula on friction and wear property was explored, and the surface topography of the friction material after wear was observed through SEM to study the wear mechanism. The results show that crystalline flake graphite influences friction coefficient most, coke influences wear rate most. The change of resin content will change the wear mechanism of friction materials.The wear mechanism is changed from fatigue wear and abrasive wear into single abrasive wear along with the increasing of resin content, and the wear pattern is changed into adhesive wear and abrasive wear for the friction material with too much resin content. High resin content will lead heat fading due to the formation of a dense carbide layer in friction surface and the formation of air cushion film in friction interface. Low resin friction materials have higher porosity with a bright and clean surface and stable friction coefficient.
