Abstract
The preferred embodiment of the armor plate composite according to the invention is composed of four main components, viz. the ceramic impact layer, the sub-layer laminate, the supporting element and the backing layer. The ceramic impact layer is excellently suitable for blunting the tip of a projectile. The sub-layer laminate of metal sheets alternating with fabrics impregnated with a viscoelastic synthetic material is perfectly suitable to absorb the kinetic energy of the projectile by plastic deformation, sufficient allowance for said plastic deformation being provided by the supporting honeycomb shaped layer. The backing layer away from the impact side and consisting of a pack of impregnated fabrics still offers additional protection. The optimum combination of said four main components gives a high degree of protection of the resulting armour plate at a limited weight per unit of surface area.
