  • High coefficients of friction with the least possible wear are required in the case of tool devices for material removal, for example in the case of grinding devices.
  • Other examples include clutches or brakes that utilize the frictional force to transmit torque or to accelerate or decelerate component motion.
  • Frictional and wear behavior of components are matched functional pads are used.
  • Conventional coverings are made up of a large number of material components, with each material component contributing proportionally to the fulfillment of certain requirements on the covering properties.

  • Typical is the layered structure of the brake pad, the individual layers usually take over certain functions.
  • the surface contact of the brake lining 100 for example, to a brake disc, via a covering material 10, which is present as an outer layer.

  • the metal foam used exclusively takes on the task of a reinforcing structure for the brake lining, whereas the wear protection and sufficiently high coefficients of friction are determined exclusively by the material composition of the filling structure.
