摘要： Disclosed herein is a wet paper friction material for vehicles. The wet paper friction material comprises: a matrix containing a hardwood pulp in an amount of about 40 to 50% by weight; a spherical silica in an amount of about 16 to 21% by weight; a friction modifier in an amount of about 5% by weight or less but greater than 0% by weight; and a filler constituting the remaining balance of the wet paper friction material, and all the % by weights are based on the total weight of the wet paper friction material.

摘要： A multilayer paper-based wet friction material of an automotive auto transmission may improve noise and vibration characteristics, heat resistance, wear resistance, compression resistance, and oil absorbency. The paper-based wet friction material of an automotive auto transmission includes: a first layer using cellulose pulp as a matrix and including a first functional additive; a second layer stacked on the first layer, using the cellulose pulp as the matrix, and including the second functional additive; and a hydrogen bonding layer mediating between the first layer and the second layer. The cellulose pulp of the first and second layers is cotton linter.

摘要： This invention relates to a paper friction material and a method of manufacturing the same, wherein the paper friction material is configured such that dispersibility and bondability are increased between a filler and a matrix. The paper friction material which is suitable for use in a vehicle, includes a friction base including pulp and a coating layer formed on the friction base using a mixture of latex and a functional material. The OH reactive group of the pulp and the aromatic ring of the latex are hydrogen-bonded so that the friction base and the coating layer are coupled with each other.
