Abstract
A dry friction device, in particular a clutch friction wheel or a brake disc for a motor vehicle, includes at least one friction liner made of a dry friction material containing reinforcing fibers. Such a friction material comprises a mat of fibers impregnated with a thermosetting resin, the fibers having a length of at least 40 mm. Glass fibers are preferably incorporated into the mat.
Claims13
A friction material for a dry friction device manufactured without the use of an organic solvent, the material comprising a mat of fibers impregnated with a thermosetting resin, the fibers having a mean length of 4 cm to 12 cm said mat further including dust, wherein said mat is without an organic solvent.
A friction material for a dry friction device manufactured without the use of an organic solvent, the material consisting essentially of a mat of fibers impregnated with a thermosetting resin, the fibers having a mean length of 4 cm to 12 cm, and wherein said mat is without an organic solvent.
A friction material for a dry friction device manufactured without the use of an organic solvent, the material comprising a mat of fibers impregnated with a thermosetting resin, the fibers having a mean length of 4 cm to 12 cm and the mat without an organic solvent.
A friction material for a dry friction device manufactured without the use of an organic solvent, the material comprising a mat of fibers impregnated with a thermosetting resin, the fibers having a mean length of 4 cm to 12 cm and said mat further including dust obtained from the rectification of friction liners, wherein said mat is without an organic solvent.
A friction material for a dry friction device manufactured without the use of an organic solvent, the material comprising a mat of fibers impregnated with a thermosetting resin, the fibers having a mean length of 4 cm to 12 cm and said mat further including powder and dust, wherein said mat is without an organic solvent.
