Abstract
A method of producing friction materials is capable of avoiding the problems in work environment due to the coarse particulates or organic solvents while producing the friction materials. The method includes processes of mixing under dry condition raw materials consisting primarily of thermosetting resin binders, fibrous reinforcing materials and friction modifiers, adding and mixing adhesives consisting of mixture of water and alcohol with the raw mixture so that the raw materials are wet and have viscosity. Afterwards, the wet raw mixture is granulated to form a granule material, dried, and heated-and-pressed to form a final product.
