  • Patent number: 9587695
    Abstract: A friction material intended to equip a device for applying friction in a liquid medium, including a fiber mat impregnated with a heat-curable resin. The fiber mat consists of fibers whose length is greater than or equal to 12 mm, and is teased, coated and needled. The friction material features a porosity greater than or equal to 30% by volume and less than or equal to 60% by volume. The friction material includes activated charcoal loads whose specific surface is between 500 m2/g and whose mass content in the friction material is greater than or equal to 5% by weight and less than or equal to 15% by weight.

  • Publication number: 20140299440
    Abstract: A friction device has a center axis (A) and a mid plane (P) perpendicular to the center axis (A). The friction device comprises first and second shields coaxial to the center axis (A) and pieced together to form a radially emerging peripheral slot between internal faces thereof, first and second friction linings fixed to external faces of the first and second shields, first connecting torques made in one piece with the first shield and having a circumferential orientation, second connecting torques made in one piece with the second shield and having a circumferential orientation, and a progressiveness element disposed in the peripheral slot and pressed between the internal faces of the first and second shields. The second connecting torques are inclined with respect to a plane of the second shield towards the mid plane (P) of the friction disc. The progressiveness element at least partly comprises an addition silicone.

  • Patent number: 6336540
    Abstract: The invention proposes a device using friction in a liquid medium having a support, notably metallic, on which an interface surface forms a support for a friction lining, with a flat annular shape overall, produced from a friction material which has a porous structure with communicating cells and which has areas (M1, M2, M3) with different controlled porosities. The method of manufacturing the friction lining including a step of moulding under pressure, whilst the interface surface of the support has at least one groove in which there extends the friction material moulded under pressure in order to constitute an area of controlled porosity (M1, M2) greater than the mean porosity (M2, M3) of the body made from friction material constituting the lining.

  • Patent number: 6135258
    Abstract: A friction liner having a flat, annular general form, for a friction device designed to operate in a liquid medium, consists in particular of a clutch friction wheel or a brake disc, especially for an automatic gearbox or associated with such a gearbox, or a synchronising ring or cone for a manual gearbox. Such friction devices are intended in particular for motor vehicles. The liner is made of a friction material consisting of a mat of fibers impregnated with a thermosetting resin. After a final curing step while the liner is being moulded under pressure, this material has a porous structure with intercommunicating cells. The liner includes zones having different controlled porosities.
