A friction material (18) includes a resin and a fibrous base material impregnated with the resin. The fibrous base material has a single ply, and includes a plurality of aramid fibers present in a first amount, a plurality of polyacrylonitrile-based carbon fibers present in a second amount that is less than the first amount, a plurality of carbon particles present in a third amount that is less than or equal to the second amount, a plurality of mineral fibers present in a fourth amount that is less than or equal to the second amount, and diatomaceous earth present in a fifth amount that is greater than the first amount. A friction member (10) for operatively contacting a lubricated surface (12) includes a substrate (16) and the friction material (18). The friction material (18) defines a first surface (20) bonded to the substrate (16) and a second surface (22) configured for operatively contacting the lubricated surface (12).
