PROCESS FOR THE PRODUCTION OF A FRICTION MATERIAL BASED ON A SHEET-LIKE CARBON FIBRE WOVEN FABRIC FOR WET-FRICTION ELEMENTS AND FRICTION MATERIAL PRODUCED BY THE PROCESS

摘要

Production of a friction material for wet-friction elements, comprises impregnating sheet-like carbon fiber woven fabric with a binder to form a binder-impregnated fiber material; curing the binder-impregnated fiber material over a curing period at a curing temperature higher than ambient temperature; and mechanically pressing surfaces of the binder-impregnated fiber material with a pressing mold prior to and/or during curing period.
