A sheet material suitable for use in body armour and resistant to penetration by a knife blade comprises a flexible layer (26) to which is attached a plurality of essentially identical substantially rigid plates (20). Each of the plates is based on a polygon and has, on successive sides, a waisted projection (24) and a re-entrant recess (22) configured to receive a waisted projection (24) of another like plate (20). The peripheries of the plates (20) thus interfit and the plates interlock to resist separation by movement in the plane of the plates. Each plate (20) is attached to the flexible layer by a rivet (28), or could be bonded hereto. |
