Abstract
Systems, devices, uses and methods relating to magnetorhological materials including carbon nanotubes, such as single-walled and multi-walled carbon nanotubes, are disclosed. Uses of magnetorheological materials such as in motion damping/vibration isolation are also disclosed.
Claims20
A magnetorheological material (MRM) comprising:
- a polymeric matrix;
- ferromagnetic particles;
- and
- carbon nanotubes.
1 more element
A motion damper comprising:
- a base;
- a bearing comprising a magnetorheological material comprising carbon nanotubes, the bearing having a first end attached to said base;
- a coil coupled to the base and capable of controllably submitting the bearing to a magnetic field, wherein the magnetic field changes at least one viscoelastic property of a component of the bearing;
- and
- an actuator attached to a second end of the bearing.
2 more elements
A motion damper comprising:
- a bearing comprising a magnetorheological material comprising carbon nanotubes;
- a first attachment point;
- a second attachment point;
- and
- a coil magnetically coupled to the bearing and capable of controllably submitting the bearing to a magnetic field, wherein the first and second attachment points are mechanically attached directly or indirectly to different portions of bearing.
