METHOD FOR MANUFACTURING FRICTION ARTICLE Russian patent published in 1998 - IPC

FIELD: manufacture of friction articles. SUBSTANCE: method includes molding of article from material with polymer binder. Heat treatment of the article is carried out concurrently on the side of working surface and on the side of article bearing surface. In this case, temperature of working surface corresponds to maximum temperature of article operation, and temperature of bearing surface is from 100 to 320 C. Heat treatment of the article is carried out at pressure of 6-60 MPa for 2-20 min. Friction articles are used for brakes and friction units of machines and mechanisms, in particular, for manufacture of friction linings of automatic brakes, blocks of belt brakes of drilling rigs and other articles molded from powdery materials with polymer binder and reinforced with fibers. EFFECT: higher wear resistance of articles, stable quality of articles and increased productivity of heat treatment. 2 tbl
