Abstract

The invention belongs to the technical field of a friction plate for a vehicle, in particular to a low-noise high-metal friction plate for a military vehicle and a preparation method thereof. The rawmaterials of the low-noise high-metal friction plate comprise the following components in percentage by weight: 5-20% of Ni3Al powder with a carbon nano tube, 5-15% of sponge iron powder, 7-30% of metal fiber, 7-21% of nonmetal fiber, 5-15% of artificial graphite, 5-8% of resin, 2-5% of rubber and the rest of calcium carbonate. The preparation method comprises the steps of weighing and mixing thecomponents according to the designed proportion, conducting hot pressing molding, curing and machining, and thus obtaining the low-noise high-metal friction plate for the military vehicle. Under the premise that the density of the metal friction plate is not greatly reduced, the brake noise incidence is greatly reduced. When being used on the special military vehicle, the high-metal-content friction plate has good weather resistance and corrosion resistance and solves the technical bottleneck of the existing friction plate for the military vehicle in use.

Description

technical field [0001] The invention belongs to the technical field of friction plates for vehicles, and in particular relates to a low-noise, high-metal military vehicle friction plate and a preparation method thereof. Background technique [0002] Military vehicles have a heavy body and a heavy load. They are used in various climatic conditions such as severe cold and hot summer, and are used in various harsh natural environments such as sandy land, swamps, and rainforests. The requirements for braking materials are much higher than ordinary vehicles. The friction material used for braking is required to have a high coefficient of friction, so that it can brake quickly and efficiently in harsh environments. With the current research and development and preparation technology of the friction plate, in order to obtain a high and stable friction coefficient, it is necessary to use high-strength metal components, such as steel or copper fibers and powders, while ensuring the s...
