る。Therefore, this type of friction material is molded into a friction pad that is always removable, and it wears out little by little when it exerts frictional force on the friction surface, so if the amount of friction exceeds a certain range, it should be replaced with a new one. Since it is a consumable item that is used in various situations such as replacing friction materials, improving the wear resistance of the friction material not only improves the reliability of the friction material itself, but also improves the reliability of the friction material itself (see above).
It is clear that the exchange period of the depleted pad JtlJ can be extended for a long period of time, leading to a reduction in the running costs of industrial machinery and the like.

とを知得して本発明を完成させたものである。That is, the inventor of the present invention focused on iron powder, which has been used as a filler in the past, and conducted extensive research on the relationship between these and wear resistance using various iron powders. When scaly iron powder is used as the material, a friction material with P8A wear resistance of 1 can be obtained compared to when other iron powders such as l″4′ are used or sprayed iron powder is used. The present invention was completed based on this knowledge.

加する。In addition, as the filler used in the present invention, those used in conventionally known asbestos-based or semi-metallic yarn-wrapped materials can be used in the same way, but fillers with different blending amounts depending on the difference in Mohs' hardness may be used. Good r11!1-The result is good. That is, fillers with a Mohs hardness of 45 or less include graphite, molybdenum disulfide, Teflon, polyester polyester, and moisturizers such as cashew dust. There are materials that have an IT effect, barium sulfate, calcium carbonate, etc., but it is preferable to mix these materials in a volume ratio of 5 to 65. Outside this range, V, J, and wear and tear occur. Only friction materials with inferior properties can be obtained. Among the fillers having a Mohs hardness of 45 or less, graphite is particularly effective in increasing wear resistance, but in this case, the preferable amount to be used increases to 5 to 50 vol.

By appropriately selecting and blending 1 filler material with a volume factor of 1 to 20 and classified according to the Mohs hardness described above, it is possible to obtain friction resistance with an increase in wear resistance, but if no filler is used at all, It has been found that if it is not used, a friction material with the desired friction performance cannot be obtained.
