FRICTION MATERIAL PREPARATION METHOD Russian patent published in 2004 - IPC

FIELD: polymer materials.

SUBSTANCE: invention relates to technology of preparing compositions based on high-molecular compounds, in particular to methods for preparing polymeric composites suited to manufacture of products appropriate for use in brake and friction systems. Method of invention comprises mixing polymeric binder with dispersed and fibrous fillers in cup-type mixer (chaser mill), wherein gap between cup bottom and calendars is set to be 0.5 to 1.0 the length of filler fiber. Polymeric binder is in the form of powder with particle size 10 to 100 mcm. When filler with rigid fibers is used, material thus prepared is supplemented by 1 to 5% of a liquid component.

EFFECT: reduced power consumption and improved quality of produce.
