Mentioning ceramics, people would spontaneously think of dishware, housewares, construction and craftwork. The application of ceramics in machinery industry is due to its hard character, temperature resistance, wear resistance and crush resistance. Turbine blades and rocket motor injectors all utilize ceramic materials. In auto, ceramics are used for making exhaust valves and plungers as well as being applied in ceramic brake pads and ceramic / natural fiber resin semimetal environmentally friendly brake pads which are featured by temperature resistance, wear resistance, stable brake, environment friendly, less abrasion to brake disc, etc.
According to traditional definition of brake materials, asbestos brake pad should contain asbestos, while semimetal brake pad large amount of metal materials, so that the ceramic brake pad plentiful ceramic materials. The so-called ceramic brake pad is such a kind of brake material that asbestos-free and contains ceramic. It is characterized by non-asbestos and non-metal and excels other brake materials in performance: temperature resistant, stable friction coefficient, small abrasion, soot-free, no antithesis abrasion, noise-free, and environmentally friendly.
Ceramic material is widely used as a composite material, and the ceramic wood and ceramic brake material are derived from it. Accordingly the notion of ceramic brake material has been extended, besides it includes ceramic material and ceramic raw material, that is, the ceramic brake material is made through sintering to mould by high temperature from the brake material with ceramic material. |
