Abstract
The addition of fibrillated acrylic fiber to non-asbestos type friction material compositions provides marked improvement in the flexural strength, stiffness and structural integrity of preforms used in the manufacture of friction elements. The consequent handling characteristics of the preform provide improvement in the manufacturing of the friction element.
