Abstract:
A composite sheet comprising:(a) a ferromagnetic substrate having a thickness between about 2 and about 5 mils, the substrate having opposing first and second major surfaces;(b) a first polymer layer laminated to the first major surface of the ferromagnetic substrate, said first polymer layer having a thickness between about 1 mil and about 15 mils; and(c) a second polymer layer having a thickness between about 1 mil and about 15 mils laminated to the second major surface of the ferromagnetic substrate, sandwiching the ferromagnetic substrate between the first and second polymer layers and forming a composite sheet peripheral edge that, when subjected to an in-plane force sufficient to cut human skin, will tend to buckle rather than cut skin.
