In order to prepare brake lining to develop a new friction material from the protecting environment,the composite mineral fiber and some filler without environmental pollution were selected and prepared by using hot press method.The mechanical properties,friction and wear properties of the composites were also investigated.The results showed that the impact strength was 2 383.9 J/m2 and the Rockwell hardness was 71.3.The friction coefficient decreased with the disc temperature increasing,it was steady and its deviation was low.The deterioration rate of the friction materials was 38.4%.The specific wear rate was increased with the temperature elevating.It was concluded that the mechanical properties and the friction and wear properties of the friction materials satisfied the requirement of National standard.
