Abstract

A method of producing friction elements composed of fillers or fillers that include at least about five percent by weight of asbestos fibers bonded together by a thermosetting resin and comprising: incorporating the mixture of the fillers and resin to a die cavity adjusted to the geometry of the friction element and apply a predetermined amount of initial pressure to the mixture during an initial state at a substantially constant volume, which is only a fraction of the final pressure, during a enough waiting time to expel practically all the trapped air in the mixture; then, during a second phase, apply pressure by gradually increasing it until the final value determined as the one that produces the desired density for the mixture; and then removing the pressed article from the die cavity and subjecting it to a time-temperature curing cycle, to achieve the curing of the thermosetting resin.
