Problems solved by technology

Its advantage is one-time molding, powder friction raw materials can be fully utilized in the material composition, and the production cost of the friction plate is low; its disadvantage is that the pore structure of the friction material cannot be controlled, the compression rebound that affects the friction performance cannot be adjusted, and the friction coefficient Low, large dynamic / static friction difference
The introduction of paper-based friction materials in the traditional sense mainly uses asbestos as a reinforcing fiber matrix, and utilizes asbestos fibers with high tensile strength, high flexibility, chemical and thermal erosion resistance, and low prices; but asbestos fibers can cause asbestosis , pleural mesothelioma and other diseases
