Abstract: With the development and advancement of society, higher speed and safety, more comfortable and environment friendly are required for automobiles and trains. It is urgent to improve the integrating properties of brake friction materials. This paper reviews the progress in research of the four components in the organic frictional materials, i.e. organic binders, reinforcement fibers, friction modified agents and fillers, also introduces some theory studies in this field, and desires to provide some information accumulation and research ideas for developing high performance friction materials.
