Title:
FRICTION-MATERIAL FILLER
Document Type and Number:
WIPO Patent Application WO/2016/175284
Kind Code:
A1
Abstract:
The present invention provides a friction-material filler that has excellent abradability and in which enhanced dispersibility in resins is expected. The friction-material filler is characterized in that magnetite is contained as the main component and that the average particle size ranges from 10 to 100 μm. The friction-material filler can be manufactured by obtaining a granulated substance having a predetermined size by using one or more components selected from magnetite particle powder, hematite particle powder, and goethite particle powder, whose average particle sizes range from 0.05 to 5.0 μm, and by firing the obtained granulated substance within a temperature range from 500 to 1200 ºC.
