  • Paper friction material and method of manufacturing the same
    Patent number: 10655687
    Abstract: 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.
    Type: Grant
    Filed: November 15, 2018
    Date of Patent: May 19, 2020
    Assignees: Hyundai Motor Company, Jinmyung Frictech Co., Ltd., Kia Motors Corporation
    Inventors: Yoon Cheol Kim, Jai Min Han, Min Gyun Chung, Jae Young Lee, Byung Chan Lee, Yoon Joo Rhee, Sung Jin Hong, Eun Pa Cho, Chi Deuk Ahn
