  • Magnetorheological elastomers (MREs) with polynorbornene as a carrier medium, processes for producing such elastomer composites and their use
    Patent number: 8123971
    Abstract: The invention relates to composites made of an elastic carrier medium comprising polynorbornene (PNR) and magnetisable particles which are polarized reversibly in a magnetic field. Thus the mechanical properties, such as e.g. storage modulus G? (describes the elastic behavior or the energy storage) and loss modulus G? (describes the viscous behavior or the energy dissipation), of such elastomer composites can be increased rapidly and reversibly within wide limits (up to approx. two orders of magnitude) as a function of an external magnetic field. Wide-ranging application possibilities are produced herefrom, e.g. for adaptive damping systems, in which the damping force can be adjusted via the strength of the magnetic field.

  • Magnetorheological elastomers and use thereof
    Patent number: 7608197
    Abstract: The present invention relates to magnetorheological elastomers comprising at least one non-magnetizable elastomeric carrier medium and magnetizable particles contained therein and also to the use thereof. In the case of MREs of this type, the mechanical properties, such as the rigidity modulus, can be changed reversibly by an applied magnetic field.
