Abstract

The invention discloses a phenolic resin modified non-metallic ceramic friction material. The material comprises, by weight, 6-10 parts of modified phenolic resin, 6-8 parts of nitrile rubber powder, 18-24 parts of ceramic fibers, 4-8 parts of carbon fibers, 10-14 parts of vermiculite, 2-4 parts of wear-resistant carbon black, 10-14 parts of a friction stabilizer and 12-14 parts of a filler. The phenolic resin is modified to make the modified phenolic resin have good performances; the modified phenolic resin is applied to prepare the ceramic friction material, so the friction resistance, the strength and the heat resistance of the prepared ceramic friction material are improved; and the phenolic resin modified non-metallic ceramic friction material contains no metal components, solves the problem of damages of existing friction materials to brake discs, has the advantages of stable friction coefficient and small noises, and can be widely used in automotive brake systems.

Description

technical field [0001] The invention relates to the technical field of ceramic friction materials, in particular to a metal-free ceramic friction material modified with phenolic resin. Background technique [0002] With the development of vehicles in the direction of environmental protection, high speed and heavy load, people put forward higher requirements on the performance of automobile braking materials, especially in high temperature braking, the stability and safety of materials are very important. At present, the automotive braking system mainly uses semi-metallic friction materials, non-asbestos organic friction materials (NAO), powder metallurgy friction materials, ceramic friction materials, etc. With the continuous development of friction materials, ceramic friction materials have been widely used and promoted along with their own advantages, and have developed rapidly in recent years. However, traditional ceramic friction materials are all for ceramic friction ma...
