Abstract
Official abstract text for this publication.
One exemplary embodiment may include a friction material having a base layer and a secondary layer over the base layer. The secondary layer may include carbon particles having a tightly controlled particle size distribution.
First claim
Opening claim text (preview).
We claim: 1. A friction material comprising a base layer and a secondary layer over the base layer, the secondary layer comprising carbon particles having a tightly controlled particle size distribution in which about 30 to about 60 wt. % of the carbon particles are sized between about 105 and about 210 microns and about 20 to about 30 wt. % are sized between about 74 and about 105 microns, and wherein the base layer comprises an upper surface area and the secondary layer covers about 50% to 100% of the upper surface area, wherein the carbon particles constitute the entirety of the secondary layer.
