Patent ID: 7749562

Claim:
A method for producing a frictional material comprising: providing a porous base material comprising fibers and fillers, the fibers comprising less fibrillated aramid fibers and carbon fibers, and wherein the fibers constitute about 70 to about 85 weight percent of the porous base material; saturating the porous base material with a saturant comprising at least one resin material and nanoparticle-sized friction modifying particles such that a plurality of the nanoparticle-sized friction modifying particles are deposited on the fibers and fillers of the porous base material to an average thickness of up to about 200 μm, the nanoparticle-sized friction modifying particles having an average diameter size from about 10 nm to about 150 nm; and curing the saturant at a predetermined temperature for a predetermined period of time.
