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.

摘要： Provided herein, inter alia, are a carbon fiber-reinforced polymer composite and a method for manufacturing the same. The carbon fiber-reinforced polymer composite may improve interfacial bonding force by modifying the surface of carbon fibers with an amphiphilic block copolymer and then forming a composite of the surface-modified carbon fibers with a polymer.
