Abstract

The invention belongs to the technical field of brake materials, and particularly relates to a friction material, a carbon ceramic brake pad formed through preparing of the friction material, and a preparing method of the carbon ceramic brake pad. The friction material comprises, by weight, 8-16 parts of carbon ceramic fiber, 1-6 parts of steel fiber, 3-12 parts of mineral fiber, 8-16 parts of chemigum modified phenolic resin, 5-11 parts of powder chemigum, 4-11 parts of petroleum coke, 9-22 parts of barium sulfate, 1-5 parts of polyacrylonitrile fiber, 6-16 parts of heavy magnesium oxide, 4-12 parts of kaolin and 2-8 parts of silicon dioxide. The above raw materials are mixed to form the mixture and placed into a die to be pressed and cured into a blank, the blank is heated and cured, andthe carbon ceramic brake pad is obtained. The brake pad has the beneficial effects of being small in abrasion thickness and long in service life; the tolerable temperature of the friction material ishigh, the problem of brake failures caused by the high brake pad temperature during frequent braking is solved, and the driving safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of brake materials, and in particular relates to a friction material, a carbon-ceramic brake pad prepared therefrom and a preparation method thereof. Background technique [0002] In modern society, automobiles, new energy vehicles, etc. are undoubtedly irreplaceable modern tools for human transportation on land, and play a pivotal role in society. With the development of society, human beings have higher and higher requirements for vehicles. , such as low energy consumption, lightweight, safe and reliable, comfortable ride, etc. Brake pads are the key components of Class A of the braking system, and their performance is directly related to the safety and reliability of automobile operation. Brake pads are generally composed of steel backs and friction materials bonded to the steel backs. When braking, the brake pads are squeezed on the brake disc or drum to generate friction, so as to achieve the purpose o...
