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.
