Research Progress of Phenolic Friction Materials

The heat resistance,toughness and friction property ofphenolic resin can be improved by chemical modification and blending modification, so that phenolic products can meet the needs of friction materials for many kinds of application. From the aspects of chemical modification,blending,multiple components modification, the research progresses of phenolic friction materials were reviewed. The multiple components modification (including chemical modifier,plastics,rubber,fiber,metal powder,inorganic nano powder) is the future research trend was pointed out. Enhancing the friction and wear properties of phenolic materials and its high temperature resistance and mechanical properties at the same time is the development direction in the future.
