Properties of Resin-based Composite Friction Materials with Different Contents of Modified Bauxite

By adding modified bauxite by 4%-12% (mass fraction) and reducing the addition of phenolic resin, resin-based composite friction materials were prepared, and the mechanical properties, anti-fade properties and friction and wear properties of the resin-based composite friction materials were studied. Experimental results show that, after adding 8%(mass fraction) modified bauxite, hardness, flexural strength and impact toughness of the composite decreased slightly, but still in the high level, and friction coefficient increased considerably. The high temperature anti-fade coefficient of the composite friction materials increased by nearly 12% than the material without modified bauxite, and they exhibited better anti-fade properties.
