  • Products made to customer specifications

Benefits

  • Designed to defeat threats up to Level 1V NIJ, when used with an appropriate backing system
  • Monolithic tiles can enable weight savings of more than 10% over mosaic designs. Ease of assembly offers cost reductions
  • Ergonomically designed for user comfort
  • ISO 9001: 2000 approved supplier

Recommended Thickness of Monolithic Tiles

The table gives an indication of the recommended ceramic thickness to be used against specific rounds of ammunition for body armour. Precise thickness of the ceramic will be determined by the type of backing material used.

This assumes plate backed with G.R.P. or aramid composite backing of areal density of up to 6Kg/m2 (1.2lb/sq.ft) and the composite plate is used in conjunction with aramid fabric ballistic vest of similar areal density capable of defeating 9mm parabellum F.M.J rounds.
