Abstract

The invention relates to a friction element (1), comprising a main body (2) having a friction layer (5), characterized in that the friction layer (5) has an arithmetic average roughness value Ra according to DIN EN ISO 4287 between 3 μm and 10 μm, a wave depth Wt according to DIN EN ISO 4287 of at least 30 μm and a mean groove width Rsm according to DIN EN ISO 4287 of at least 150 μm. Pores of the friction layer have a pore size which is selected from a range with a lower limit of 25 μm and an upper limit of 900 μm.
