Problems solved by technology

However, a problem with graphite that is generally used is that when its added amount increases, the coefficient of friction decreases
Therefore, the use of highly elastic graphite has been investigated, but the highly elastic graphite is still not a sufficiently satisfactory material

Embodiment 1 to 3

[0046] Elastic partially graphitized coke (RGC 14A from Superior Graphite Co.) was added in a proportion of 0.5 to 2.5% by volume. With this formulation, as described above, after dry mixing, preforming, thermoforming (see Table 1 for temperature and pressure), and heating, grinding was carried out to obtain the final product.

Abstract

Anon-asbestos friction material is provided with a fibrous base material, a friction modifier, and a binder, wherein a partially graphitized coke is blended in a ratio of 0.5 vol % to 2.5 vol %. By blending the partially graphitized coke, compression strain of the friction material is adjusted so as to improve brake feeling without deteriorating friction properties.

Description

[0001] This application claims the benefit of foreign priority from Japanese Patent Application No. 2006-160963 filed on Jun. 9, 2006, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to friction materials for brakes of motor vehicles, railway vehicles, industrial machines, etc., and to materials exhibiting improved heat resistance, wear resistance, and brake feel, especially pedal feel, with little thermal degradation friction material. Background technique [0003] Generally, friction materials for brakes and the like have been manufactured by blending a fiber base material, a friction modifier, and a binder and performing a production process including preforming, thermoforming, finishing, and the like. As materials for friction materials, fibrous base materials such as organic fibers, inorganic fibers including glass fibers, and metal fibers including copper fibers are used; organic / inorganic fricti...
