摘要:
A method for producing a multi-layered wet friction material includes providing a bottom layer, providing a top layer produced independently of the bottom layer from different materials, and bonding the bottom layer to the top layer. The bottom layer and the top layer may be produced from different formulations and supplied as raw papers. A formulation of the top layer may include twenty to sixty percent (20%-60%) filler, ten to forty percent (10%-40%) wood pulp, five to ten percent (5%-10%) aramid, and twenty-five to thirty-five percent (25%-35%) phenolic resin. A formulation of the bottom layer may include ten to fifty percent (10%-50%) filler, ten to forty percent (10%-40%) wood pulp, five to ten percent (5%-10%) aramid, five to fifteen percent (5%-15%) carbon, and twenty-five to thirty-five percent (25%-35%) phenolic resin.
