METHOD OF MANUFACTURING FRICTIONAL PRODUCT Russian patent published in 2002 - IPC

Abstract RU 2194057 C2

FIELD: frictional materials. SUBSTANCE: invention relates to means for manufacturing abrasive- and friction- destination products. Method of manufacturing frictional product is distinguished by that, when forming blank from mixture of stapled carbon fiber and pitch powder, filaments are precipitated on filter element and their orientation is changed by velocity of compressed gas stream and by creating negative pressure gradient on filter element. EFFECT: increased reliability of frictional product manufactured according to simplified technology. 1 dwg
