【発明の詳細な説明】
本発明は高温下での摩擦性能のすぐれたセミメタリック
摩擦材に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a semi-metallic friction material that has excellent friction performance under high temperatures.

されている。Friction materials containing asbestos as a fiber component are used in the brakes of automobiles, etc. However, this friction material has problems with friction performance such as wear resistance under high temperatures, so it is difficult to use depending on the field of use. Semi-metallic friction materials are often used.

摩耗、損傷を受けることが判明した。It is made up of a material and a filler such as graphite, iron powder, barium sulfate, etc., and has superior friction performance at high temperatures compared to the friction material whose fiber component is asbestos. It has been found that under high temperatures of 500°C or higher, the organic components of the material deteriorate, leading to increased wear and, in some cases, ignition, resulting in significant wear and damage.

と考えら相る。That is, the inventor of the present invention, in order to improve the soil 81 defects of conventional semi-metallic friction materials, achieved the result of grinding at 9 degrees Celsius.
Steel fibers are coated with silica-based, silica-aluminum-based, aluminum-based, and zirconia-based inorganic compounds,
If a metallic friction material is formed from these steel fibers, a binder made of phenolic resin, and a filler such as graphite, iron powder, barium sulfate, etc., this friction material will have excellent wear performance at high temperatures of 300°C or higher. The present invention was accomplished by coating the steel fiber with the above-mentioned inorganic compound in advance.
The reason why the formed friction material exhibits excellent friction performance at high temperatures is thought to be because the presence of the coated 411 (organic compound) suppresses the deterioration of phenol town fat at high temperatures.
