Problems solved by technology

Its advantage is one-time molding, and the powder friction raw material and block rubber material can be fully utilized in the material composition structure, and the production cost is low; the disadvantage is that the pore structure of the friction material cannot be controlled, and the compression rebound performance that affects the friction effect cannot be achieved. Adjustable, low coefficient of friction, large difference in dynamic / static friction ratio
Traditional paper-based friction materials mainly use asbestos as a reinforced fiber matrix, which has high tensile strength, high flexibility, chemical and thermal erosion resistance of asbestos fibers, and thus is cheap; but asbestos-based paper-based friction materials The high temperature resistance is relatively poor, and asbestos fibers can cause diseases such as asbestosis and pleural mesothelioma, and the use of them has been explicitly banned in China

Description

technical field [0001] The invention relates to a ceramic fiber paper-based friction plate and a manufacturing method of the ceramic fiber paper-based friction plate; moving system. Background technique [0002] At present, the wet friction material commonly used in China is widely used in dry powder metallurgy molding to manufacture nitrile rubber-based wet friction plates. Its advantage is one-time molding, and the powder friction raw material and block rubber material can be fully utilized in the material composition structure, and the production cost is low; the disadvantage is that the pore structure of the friction material cannot be controlled, and the compression rebound performance that affects the friction effect cannot be achieved. Adjustment, low coefficient of friction, large difference in the ratio of dynamic / static friction. Traditional paper-based friction materials mainly use asbestos as a reinforced fiber matrix, which has high tensile strength, high flex...
