Problems solved by technology

However, the high temperature resistance of asbestos-based paper-based friction materials is relatively poor, and asbestos fibers can cause diseases such as asbestosis and pleural mesothelioma, and the use of them has been banned in China
At present, dry powder metallurgy molding is widely used in China to manufacture nitrile rubber-based wet friction plates; its advantage is that powder friction raw materials and block rubber materials can be fully utilized in the material composition structure, and it can be formed at one time, and the production cost is low; its disadvantages are: The pore structure of the friction material is difficult to control, the compression and rebound performance that affects the friction effect cannot be adjusted, the friction coefficient is low, and the ratio of dynamic / static friction varies greatly

Description

technical field [0001] The invention relates to a wet-type paper-based friction plate based on carbon fiber ceramic fiber composite reinforcement and a manufacturing method of a wet-type paper-base friction plate reinforced by carbon fiber ceramic fiber composite; the friction plate is suitable for engineering machinery, agricultural machinery, mining machinery, and heavy vehicles Clutch and brake systems in machinery such as , cars and ships. Background technique [0002] Paper-based friction materials in the traditional sense mainly use asbestos as the reinforcing fiber matrix, which has the high tensile strength, high flexibility, chemical and thermal erosion resistance of asbestos fibers, so the price is low. However, the high temperature resistance of asbestos-based paper-based friction materials 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. At present, dr...
