Abstract

The invention relates to a high-temperature wear-resisting ceramic composite fiber brake block which is manufactured by processing framework materials and auxiliary materials through material mixing, mould pressing, hot press molding and solidification procedures, wherein the framework materials comprise bismaleimide modified phenolic resin, short aramid fiber, high-purity ceramic fiber, potassium titanate fiber, mineral fiber, barium titanate and nickel; the auxiliary materials comprise molybdenum sulfide and / or tin sulfide, graphite and / or coke, acrylonitrile-butadiene rubber, mica, zinc oxide, stearic acid, barium sulfate and 4010-type antiager. The high-temperature wear-resisting ceramic composite fiber brake block solves the problems existing in the prior brake blocks, can well avoid high-speed decay and high-temperature decay, has the advantages of being good in staibility and long in service life, and is a high-temperature wear-resisting ceramic composite fiber brake block which is low in noise, high in intensity and low in pollution.

Description

technical field [0001] The invention relates to a brake pad in the field of friction materials, in particular to a high-temperature wear-resistant ceramic composite fiber brake pad. Background technique [0002] At present, the friction materials for making brake pads are mainly divided into traditional asbestos-type brake pads, metal hybrid brake pads and ceramic-based friction material brake pads. Among them: the outstanding problems of asbestos-type brake pads are low strength, poor thermal stability, and easy wear, which have been gradually eliminated; the main material of metal-mixed brake pads is steel fiber as a reinforcing fiber, which has the advantage of high metal content and high wear resistance. Strength and thermal conductivity, but its outstanding problem is that high content of metal is likely to cause increased noise and wear of the brake system, and requires higher brake pressure to be used together; ceramic-based friction material brake pads are new materi...
