Abstract
A method of making a wet friction material includes coating a first outer surface of a cellulose layer with a friction coating; placing a matrix of fibers and filler particles on a second outer surface of the cellulose layer; and saturating the matrix of fibers and filler particles with a binder and curing the binder to join the matrix of fibers and filler particles together to form a wet friction material base layer and to join wet friction material base layer to the second outer surface of the cellulose layer.
