A ceramic armour element for use in armour

A technology of ceramics and components is applied in the field of armor panels providing anti-ballistic performance, which can solve the problems of falling off of tiles and adjacent tiles, destroying panels, and reducing the protective performance of panels, so as to improve the anti-ballistic performance and improve the level of protection.

Problems solved by technology

Energy is also transmitted through the thickness of the tile, which can cause the hit tile and adjacent tiles to dislodge from the backing if the tile is bonded to the backing
Complete destruction of the tiles leaves large areas of the panel without the ceramic layer, reducing the panel's protection against re-impacts near the same location

Embodiment Construction

[0021] FIG. 1 shows a ceramic armor element 10 . When the ceramic armor element 10 is viewed in the direction indicated by Z, the ceramic armor element has a hexagonal cross-sectional shape. The ceramic armor element 10 has lugs 12 , 14 , 16 , 18 , 20 , 22 on each side of the ceramic armor element. The element has a flat lower surface 24 and a convex upper surface 26 . The convex upper surface serves to dissipate the energy from the initial impact of the projectile over a larger area than if the element had a flat upper surface.

[0022] FIG. 2 shows an array of hexagonal ceramic armor elements comprising element 10 and identical elements 100 , 200 , 300 , 400 , 500 , 600 . The hexagonal array is arranged such that the lugs 12 , 14 , 16 , 18 , 20 , 22 on the ceramic armor element 10 cooperate with adjacent ceramic armor elements 100 , 200 , 300 , 400 , 500 , 600 . The lugs 101, 201, 301, 401, 501, 601 on the adjacent elements 100, 200, 300, 400, 500, 600 are arranged on the...

Abstract

The invention concerns an armor panel to provide protection from projectiles. The present invention relates to an armor panel comprising a layer of hexagonal ceramic armor elements (10) having a spacing means in the form of lugs (12, 14, 16, 18, 20, 22) which are on the side of the ceramic armor element 10 and arranged to co-operate with adjacent ceramic armor elements (100, 200, 300, 400, 500, 600) and form a bond line in the space (48) between elements.

Description

technical field [0001] The present invention relates to an armor panel. More particularly, the present invention relates to armor panels that provide ballistic resistance. Background technique [0002] Ceramic armor is well known in the art of providing ballistic protection and comprises panels assembled from individual ceramic elements. Prior art ceramic armor panels comprise ceramic elements assembled in an array having basic element shapes. Ceramics are very hard and physically stable, making them highly resistant to melting, bending, stretching, corrosion or abrasion. For example, ceramics are known for use in armor, insulators and artificial joints, which can be made, for example, of aluminum oxide (alumina). The basic ceramic element shape for the armor may be cylindrical, spherical or tile-shaped (eg, square or hexagonal). [0003] In ceramic armor, momentum and kinetic energy absorption are important for two reasons. The first is to prevent the armor from being ...
