Abstract
A method for producing a synchronizer ring includes providing a ring body made of metal and having a conical connecting surface, providing a friction ring, corresponding to the connecting surface, made of a composite material of carbon fiber bound with a resin, adhesively bonding the friction ring to the connecting surface, and pyrolyzing exclusively an outer layer of the friction ring which is remote from the connecting surface.
