A flexible sheet material suitable for use for example as body armour comprises a plurality of individual rigid plates (10) all lying in the same plane and each both interfitting and interlocking with its adjoining plates (10) by having interengaging waisted projections (11) and re-entrant recesses (14) on successive sides. The edge wall profile of each plate is shaped to co-operate with the edge wall profile (figure 2) of the adjoining plate whereby relative separation of those plates (10) in the direction normal to the general plane of the sheet material is resisted. The edge profile may be V-shaped, with the edge profile of the adjoining plate (10) complementary form, or the angle of the edge wall of one plate (10) may vary around the periphery of one plate (figures 3, 4a, 4b), with the edge wall profile of the adjoining plate (10) matching the edge wall angle of said one plate. |
