  • Publication number: 20230243395
    Abstract: Expanded graphite and/or vermiculite are introduced into the friction lining mixture to eliminate or substantially reduce the amount of binder present therein. The friction lining at most contains from 2.5% by weight of binder. By omitting/reducing binder, the production is very stable and the friction linings can be easily reproduced. The process steps of hardening (including the hardening furnace) and scorching (including the necessary equipment) can be omitted when making such friction linings.

  • Patent number: 11662285
    Abstract: The invention relates to a device for ascertaining mechanical properties, for example, the natural frequency, the damping or the natural vibration mode of a test specimen containing ferromagnetic material components, in particular a brake pad for a motor vehicle. An electromagnetic actuator, in particular an electromagnet, is provided for exerting a magnetic attractive force onto the test specimen so that the actuator exerts a force impulse that imparts the test specimen with vibrations whose spectrum of vibration contains at least one natural frequency vibration of the test specimen.
