Problems solved by technology

[0002] At present, the brake pads made of composite friction materials have low overall performance and various performance problems, such as insufficient strength and toughness, large thermal decay at high temperature, unstable friction coefficient during the heating process of the brake, and slippage may occur These problems mainly come from the selection of friction materials
In the prior art, to solve these problems, there are too many types of raw materials used in the preparation of friction materials, some as many as 25, resulting in high cost and uneconomical; in addition, some carbon fiber friction materials are not used in the preparation process. The surface treatment of carbon fiber will be carried out, so that it is difficult to mix carbon fiber and other raw materials evenly after mixing; if the surface of carbon fiber is modified, the production process of the friction material is slightly complicated, which is not conducive to vigorous promotion

Abstract

The invention discloses a carbon fiber resin-based friction material and a preparation method thereof. The raw materials include nitrile rubber powder, mineral fiber, carbon fiber, calcium sulfate, bauxite, friction powder, aluminum oxide, white carbon black, plastic particles, white clouds resin, aramid and graphite. The manufacturing method steps are: weighing of raw materials, processing of carbon fibers, mixing of raw materials, drying of raw materials, pressing of raw materials and solidification of friction materials. The invention uses less material, is low in cost and has a long service life; at the same time, the carbon fiber is subjected to simple ultrasonic surface treatment to make it have better friction and wear performance; the invention is a brake pad with excellent performance and is worthy of vigorous promotion.
