  • Carbon fiber/flame-resistant organic fiber sheet as a friction material
    Patent number: 4256801
    Abstract: Paper base friction material in the form of a porous, flexible interfelted fibrous sheet comprised of a mixture of 25 to 65 percent cellulose fibers, 5 to 20 percent carbon fibers, 5 to 20 percent flame-resistant organic fibers, fillers, and an oil resistant elastomeric sizing. The friction material also includes a synthetic resin binder which may be incorporated during preparation of the sheet or subsequently. In use, the paper base friction material is bonded to a supporting member, preferably metal, whereby it is useful as a friction element particularly in oil, such as in automotive automatic transmissions.
