Abstract

PURPOSE: To obtain a clutch facing which does not exhibit initial fading phenomenon and has excellent wear resistance, etc., by a method wherein parallel glass fibers are impregnated with a thermosetting resin soln., and then bonded to rubber by means of rollers to produce a material which is then molded.
CONSTITUTION: A yarn strand 1 composed of glass fiber (if desired, contg. asbestos yarn) is passed through a thermosetting resin soln. 2 (e.g. a phenolic resin) to impregnate the strand 1 with the soln. 2, and then dried in a dryer 3. Then a rubber blend 5 is bonded to the resulting impregnated yarn strand by means of rollers 4 to obtain a material 6. This material 6 is wound around the central shaft part of a preforming mold to preform the material into a circular shape having a desired thickness. Then the preform is heated under pressure within a molding die to cure it, whereby the desired clutch facing can be obtd.
EFFECT: There can be obtd. clutch facing which has high centrifugal breaking strength and friction coefficient and in which there is no change in depth of wear due to variability of the rubber blend.
