摘要

Process for the manufacture of a friction material based on a fabric of carbon fiber plan for elements of friction wet and friction material produced according to the process.The present invention relates to a process for the manufacture of a friction material based on a fabric of carbon fiber plan for elements of friction clutch or wet fittings linings synchronous rings, including the impregnation of the fabric fibers of car Bono and a binder for the formation of a fibrous material (prepreg) impregnated with a binder.The invention provides that the prepreg (1) is hardened during a period of tempering at a temperature of quenching high compared with ambient temperature, and before the start and / or at least during part of the period of hardening, is mechanically pressed on their surfaces through A pressing tool (2).
