Abstract

See full text

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 comprise a magnetic material that provides a change in shape orientation of the hook elements in response to an activation signal. In this manner, the shape orientation of the hook elements can be remotely changed to provide a reduction or magnification in the shear and/or pull-off forces.
