FRICTION ARTICLE Russian patent published in 2011 - IPC B61H1/00 F16D65/04 F16D69/02 

FIELD: transport.

SUBSTANCE: invention relates to machine building, namely, to friction assembly units and parts incorporated with automotive equipment, various machinery and units. Friction article comprises polymer friction element glued to metal substrate with rough surface on the side friction element is glued onto. Height of substrate rough surface irregularities and glue layer thickness are selected from relationship where R_z is said height of irregularities and L is glue layer thickness.

EFFECT: improved operating performances due to better adhesion of friction element to metal substrate resulted from optimised irregularity height-to-glue layer thickness ratio.
