Friction material block, in particular for equipping brake pad, and associated brake pad and method

The invention relates to a friction block or layer made of an asbestos-free friction material comprising inorganic and/or organic and/or metal fibres, at least a binder, at least a friction modifier or lubricant, and at least a filler or abrasive as constituent materials thereof, the asbestos-free friction material further comprising a hydrophobic wax as a further constituent material or additive, the present invention relates to an asbestos-free friction material block or layer comprising a hydrophobic wax preferably present in the range of 0.5% to 5% by volume, the asbestos-free friction material block or layer having hydrophobicity defined as the absorption time of droplets formed by 20 +/-5 pL distilled water within the friction material is greater than 60 minutes, such that the force of separation of the friction block or layer from the metal surface to which it has been electrochemically pressed is less than 15 Nw. 由无石棉摩擦材料制成的摩擦块或层，所述摩擦材料包含无机和/或有机和/或金属纤维、至少粘结剂、至少摩擦改进剂或润滑剂以及至少填料或磨料作为其组成材料，其中无石棉摩擦材料还包含疏水性
