摘要： A fluid includes a liquid medium having iron particles mixed therein. An organic phosphonate based coating is established on the iron particles. The organic phosphonate based coating does not substantially include phosphonic acid groups at an outer surface thereof, and increases oxidation resistance of the iron particles. A method of making such a liquid medium is also disclosed herein.

摘要： A magnetorheological composition includes a mixture of a carrier medium and a particle component disposed in the carrier medium. The particle component includes a magnetic material and a nonmagnetic material. The nonmagnetic material is present in the particle component in an amount of from about 5 to about 95 parts by volume based on 100 parts by volume of the particle component. The particle component is present in the magnetorheological composition in an amount of from about 20 to about 80 parts by volume based on 100 parts by volume of the magnetorheological composition. The magnetorheological composition has an on-state yield stress at magnetic saturation of from about 0.1 to about 100 kPa.

摘要： A releasable fastener system comprises two hook portions. The hook portions each include a support and a plurality of closely spaced upstanding hook elements extending from one side thereof. When the two hook portions are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. The head elements of the hook elements are formed of a material that provides a change in directional orientation of the head elements. In this manner, the directional orientation of the head elements of the hook elements can be remotely changed to provide a reduction or magnification in the shear and/or pull-off forces.

摘要： A component defines at least one chamber that is confined by the component. The chamber has an inner surface. A filler material is disposed inside the chamber. Relative movement between the inner surface and the filler material helps dampen vibrations and other oscillations if and when the component is vibrated.

摘要： A releasable fastener system comprises a loop portion and a hook portion. The loop portion includes a support and a loop material disposed on one side thereof whereas the hook portion includes a support and a plurality of closely spaced upstanding hook elements extending from one side thereof. When the hook portion and loop portion are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. The hook elements are formed of a magnetorheological elastomer that provides a change in shape orientation and/or flexural modulus of the hook elements. In this manner, the shape orientation and/or flexural modulus of the hook elements can be remotely changed to provide a reduction or magnification in the shear and/or pull-off forces in addition to providing variable damping capabilities to the fastener system.
