FRICTION ARTICLE Russian patent published in 2006 - IPC F16D69/02 

FIELD: mechanical engineering; friction articles containing polymer composite friction members.

SUBSTANCE: proposed friction article has metal framework and polymer composite friction member consisting of layers; each layer consists of polymer matrix and fillers (or filler).Layer of friction member which is in contact with metal framework has mass ratio of matrix to filler (or fillers) which exceeds this ratio in working layer. Friction member is made of three layers. Layer between working and layer which is in contact with metal framework has ratio of matrix to filler (or fillers) more than this ratio in working layer but lesser than in layer which is contact with metal framework. Resistance of article to thermal fatigue at abrupt heating and cooling is increased due to smooth change of heat conductivity of article in layers from working layer to metal framework.

EFFECT: enhanced efficiency; enhanced resistance to thermal fatigue.
