Projectile barrier and method

Barrier structure placeable as a projectile disabling, anti-fuel-leak protective coating adjacent a vulnerable outside surface in a container designed to hold defined liquid of a certain nature, said structure comprising

• first-type barrier layer structure formed as a sheet-like expanse of an elastomeric material which is capable of imbibing such defined liquid and of swelling in the process of so imbibing such liquid, and which is substantially fully self-healing through elastomeric behavior, as well as through liquid imbibing and resultant swelling, with regard to a container-piercing projectile wound, and
• second-type barrier layer structure operatively disposed adjacent one side of said first-type barrier layer structure, and composite in nature, said second-type barrier layer structure having elemental components which are entrained in another sheet-like expanse of the same elastomeric material employed in said first-type barrier layer structure, and wherein said entrained components function as imbibers of the mentioned defined liquid, and expand, three-dimensionally, in relation to any direct contact with the mentioned defined liquid.
