This lubricating component can be selected from solid lubricants such as graphite, molybdenum disulfide, and mica powder. The preferred blending ratio of the lubricating component is 1 to 15% by weight based on the non-asbestos friction material for the final brake. If the blending ratio of the lubricating component is less than 1% by weight, brake squeal cannot be controlled, which is undesirable.

攻撃が発生してしまう。[0014] The xonotlite added to the non-asbestos friction material prepared by adding and blending the above-mentioned components has the effect of stabilizing the static coefficient of friction at a high level without attacking the other material. Generally, friction materials that do not use asbestos contain a large amount of lubricating component in consideration of brake squeal, resulting in a low static friction coefficient. Therefore, as a means to increase the static friction coefficient, it is generally known to use a friction modifier such as an abrasive. However, using abrasives may cause attacks on the other material.

If the blending ratio of xonotlite is less than 1% by weight, the static friction coefficient will not increase and the problem will not be solved. Also, 1
If it exceeds 5% by weight, the dynamic friction coefficient and static friction coefficient become high, which is undesirable because it causes squealing.

The test method was based on the JASO C436 static strength test. Furthermore, the obtained products of the present invention, existing non-asbestos-based friction materials, and comparative products 1 and 2 were subjected to wear tests using a dynamo bench testing machine using a brake system for four-wheeled vehicles, and the results were shown in Table 1. The amount of wear was measured.

ないことが判明した。[0021] Furthermore, in order to determine brake squeal, the above-mentioned friction material was attached to a four-wheeled vehicle and an actual vehicle test was conducted. As a result, as shown in Table 2, it was found that the product of the present invention had a high static friction coefficient, was stable, had a small amount of wear on the mating material, and did not generate squeal.

Comparative product 1 has a lower static friction coefficient than the product of the present invention and has not been improved. On the other hand, comparative product 2 had too high a static friction coefficient and a dynamic friction coefficient, causing squealing. For these reasons, it is considered that the amount of xonotlite added is preferably within the range of 1 to 15% by weight.
