Abstract: A light-weight wall panel for a protective enclosure includes a shell of sheet metal which encases a filler structure of a combination of penetration resisting or hard wood and metal members. The filler structure includes first and second wall structures which differ from one another by the orientation of hard wood and sheets of expanded metal which are interleaved between adjacent ones of the boards. In the first wall structure adajcent one of the major surfaces of the wall panel, the hard wood boards and interleaved metal sheets have their major surfaces oriented perpendicular to the major surfaces of the wall panel. The second wall structure adjacent the other of the major surfaces of the wall panel has layers of hard wood boards and sheets of expanded sheet metal which extend with their major surfaces parallel to the major surfaces of the wall panel. The two wall structures are fastened to each other and hence into a single structure.

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.

The bond between the metal plates of the third layer as well as between the second and third layer extends either over the whole surface or only part thereof for instance only at the edges of the armour plate.
