     potassium titanate, magnesium borate and calcium sulfate whisker modified non-metallic friction materials (designated as p, m and c) were prepared by compression moulding process. results of physical test showed that the addition of whisker greatly improved mechanical properties and slightly increased thermal stability. particularly, m exhibited the highest tensile strength and c showed the best thermal stability. the tribology properties were investigated against a special counterpart of wire rope under dry and grease lubrication conditions. results showed that potassium titanate whisker improved the wear-resistance most, and calcium sulfate whisker increased the value and stability of friction coefficient most at high sliding speed.
