Abstract

The invention relates to the technical field of brake materials, in particular to a friction material, an organic carbon-ceramic brake pad for a light-weight carbon-ceramic plate prepared from the friction material, as well as a preparation method and application thereof. The organic carbon-ceramic brake pad for the light-weight carbon-ceramic plate is prepared from the following raw materials including, by weight, 2 to 4 parts of basalt fiber, 10 to 15 parts of steel fiber, 5 to 10 parts of mineral fiber, 8 to 12 parts of phenolic resin, 5 to 10 parts of elastic particles, 6 to 10 parts of cashew nut oil friction powder, 10 to 20 parts of precipitated barium sulphate, 1 to 3 parts of acrylic fiber, 2 to 4 parts of silicon carbide, 6 to 11 parts of kieselguhr and 9 to 12 parts of glass beads. The preparation method is pressing and thermosetting forming. The organic carbon-ceramic brake pad for the light-weight carbon-ceramic plate provided by the invention is stable in structure, goodin heat resistance and friction performance, simple in preparation process, and short in preparation period, and has good compatibility with the light-weight carbon-ceramic plate and good practicability so as to form a light-weight friction pair, so that the light weight of a vehicle can be effectively realized.

Description

technical field [0001] The invention belongs to the technical field of brake materials, and in particular relates to a friction material, a mechanical carbon-ceramic brake pad for lightweight carbon-ceramic discs prepared therefrom, and a preparation method and application thereof. Background technique [0002] In the past 20 years, with the vigorous development of the transportation industry, high-speed, safe and reliable requirements have been put forward in the field of vehicles. In the research process of automobiles or some high-speed trains and racing cars, it is found that lightweight can significantly improve the acceleration stability and handling of vehicles. , and the vehicle's unsprung lightweight performance is much greater than that of the sprung lightweight, and the performance of reducing the unsprung mass by 1kg can be equivalent to reducing the sprung mass by 10-15kg. Therefore, lightweight brake discs are widely used. [0003] Lightweight carbon-ceramic br...
