Abstract:
1. A production method of a friction material, comprising: dispersing an amorphous resin selected from the group consisting of a polyimide, a polyamidoimide, a polycarbonate, a polyphenylene ether, a polyarylate, a polysulfone and a polyester sulfone in at least one component selected from the group consisting of a filler component, a binder component and a base component, wherein the dispersing is carried out in the absence of one or more of the components, to form coated particles wherein at least one of the components is coated with the amorphous resin, then mixing the coated particles with the components to form the friction material, wherein the friction material comprises 0.001 to 50 vol % of the amorphous resin.
