Abstract:
Provided by the present invention are: a non-asbestos frictional material composition containing a binder, an organic filler, an inorganic filler, and a fiber substrate, wherein, in the non-asbestos frictional material composition, content of a copper is 5% or less by mass as a copper element, content of a metal fiber other than a copper fiber and a copper alloy fiber is 0.5% or less by mass, and a titanate salt is contained therein with antimony trisulfide or zinc powders, with content of the titanate salt being in the range of 10 to 35% by mass; and a frictional material and a friction member that use the said non-asbestos frictional material composition.
