Abstract
A multi-layer friction element is disclosed consisting of carbon-carbon composite material comprising a structure layer of so-called "coarse" texture comprising segments of rovings and at least one friction layer of so-called "fine" texture comprising fibre segments. A method also is disclosed for producing the friction element by preparation of a fibrous substrate by introducing segments of roving and/or fibers into a mould preferably by means of a distribution apparatus. Further disclosed is an apparatus for automatically obtaining a fibrous substrate of predetermined texture.
