Title:
FRICTION MATERIAL COMPOSITION, FRICTION MATERIAL USING SAID FRICTION MATERIAL COMPOSITION, AND FRICTION MEMBER
Document Type and Number:
WIPO Patent Application WO/2016/103972
Kind Code:
A1
Abstract:
Provided are: a friction material composition that makes it possible to maintain a sufficient coefficient of friction in a friction material containing no copper or 0.5 mass% or less of copper under high-speed brake fade conditions resulting from repeated sudden braking at a deceleration of 0.8 G from a high speed of 200 km/h and an abnormal increase in brake temperature; and a friction material obtained by molding the friction material composition. The friction material composition includes a binder, an organic filler, an inorganic filler, and a fiber substrate. The friction material composition contains 2-5 mass% of steel fibers that contain no elemental copper or that contain 0.5 mass% or less of copper, said steel fibers having a fiber length of 800 µm or more.
