  • Molded composite armor
    Patent number: 4945814
    Abstract: The invention relates to the manufacture of composite metal armour plating comprising ceramic inserts (42) regularly disposed through the thickness and giving reliable, reproducible ballistic efficiency.The ceramic inserts are positioned at regular intervals by disposing them in enveloping shells comprising male and female portions fitting into one another in order to bring about relative predetermined positioning and leave gaps into which the actual casting metal can flow during casting.

  • Armor elements and method
    Patent number: 4760611
    Abstract: Armor element for protection against projectiles, formed by a core made of ceramic material covered with a metal envelope obtained by casting around the core a resilient alloy having high antiballistic efficiency.The envelope is strongly prestressed at casting around the ceramic core in order to inhibit the fragmentation thereof under shock due to the impact of a projectile.The invention can be applied to constructing flexible armor implements by assembling and hingedly interconnecting juxtaposed armor elements.

  • Composite armour plating
    Patent number: 4534266
    Abstract: The invention relates to composite metal armour comprising ceramic inserts arranged in a regular manner within a metal casting. To ensure that the ceramic inserts are arranged at regular intervals within the metal, each of the inserts is provided with an encasing shell including male and female portions which are receivable into the male and female portions of adjacent inserts in order to maintain the inserts in a regular pattern during casting.
