Abstract:
1. A releasable fastener system comprising: a loop portion comprising a support and a loop material disposed on a surface thereon; a hook portion comprising a support and a plurality of hook elements disposed on a surface, wherein the plurality of hook elements comprises a magnetorheological elastomer adapted to change a shape orientation and/or flexural modulus of the hook elements upon receipt of a magnetic signal; and an activation device coupled to the plurality of hook elements, the activation device being operable to selectively provide the magnetic signal to the hook elements and effectuate a change in the shape orientation and/or flexural modulus of the hook elements to reduce or increase a shear force and/or a pull-off force, and wherein the change in the flexural modulus of the hook elements provides a damping capability to the fastener system.
