摘要：Method for manufacturing an asbestos-free friction material having as

component materials inorganic and/or organic and/or metallic fibers, at least one organicbinder, at least one friction modifier or lubricant and at least a filler or abrasive. The rawcomponents of the friction material are mixed together to obtain a raw mixture which isthen molded to obtain a block or layer of friction material. The mixing step includes afirst step of hot blending of at least part of the organic binder with at least part of theother components of the friction material by a rolling mill blender that is open toatmospheric pressure at a temperature lower than the polymerization temperature ofthe organic binder but greater than or equal to its softening temperature, in order toobtain a semifinished solid product. A second step of grinding the semifinished solidproduct reduces the product to a powder.
