Abstract
A synchronizer ring () having a support body (), a conical friction surface (), and a friction layer () of a material including carbon fibers applied to the friction surface (). The material is a compacted carbon fiber reinforced plastic. A synchronizer ring of this type has a longer service life than those of the prior art, on account of the improved dimensional stability of the friction layer, and is inexpensive. Also disclosed is a method for producing the above-described synchronizer ring.
