Process for the production of friction materials. |
摘要 |
<p>A process for producing a friction material under low-temperature conditions using, as a reinforcement, one or more fibers selected from a metal fiber, an organic fiber and an inorganic fiber and, as a binder, a compounded pitch that consists of a mesophase pitch and sulfur and/or an aromatic nitro compound. The content of an optically anisotropic phase in the mesophase pitch is at least 80% and the softening point of the mesophase pitch is not higher than 270 DEG C. The friction material produced exhibits consistent friction characteristics over a broad temperature range. <IMAGE></p> |
