With the rapid development of the automobile industry, the market of automobile brake friction materials in China is also active, the demand of automobile brake pads is increased year by year, and the high-precision and high-quality production of the automobile brake pads is more needed to support the safety of automobile driving.
The automobile brake is a key part for ensuring the driving safety, is designed for reducing the driving speed of the automobile or stopping the automobile, and converts the kinetic energy of the automobile into heat energy through friction so as to achieve the aim of braking. The performance is directly related to the driving safety of the automobile. When the brake system has a fault, the fault must be eliminated in time; when the braking performance of the automobile does not reach the index, the automobile should be inspected and maintained early so as to keep good technical condition.
For a disc brake, a brake pad is fixed with a brake disc, is formed by bonding various reinforcing fibers such as ceramic fiber, aramid fiber, potassium magnesium titanate and the like with other components, and is a friction material product with various performances required by friction braking. The quality of the brake performance of the automobile depends on the quality of the brake pad, so that the quality of the brake pad is closely related to the life and property of people. The development of high speed of automobiles also puts forward more strict requirements on the production quality of brake pads, and at present, China still needs to import some friction materials of high-end automobile brake systems to meet the requirements, which is an invisible obstacle to the development of the automobile industry in China, and also hinders the development of economy in China, so that the automobile brake pad is a subject which is urgently needed to be solved before people.
The ceramic composite material has very important effect on the performance of the whole material. With the development of transportation machinery towards high speed and heavy load, higher requirements are put forward on high-performance friction materials, such as good fade resistance, shear strength, stable friction coefficient, smaller abrasion, lower noise and the like. However, the unmodified phenolic resin in the existing friction material has the defects of large brittleness, poor toughness and limited heat resistance, and can not meet the use requirements of modern automobile braking.
