Anti-leak projectile barrier and method

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

• a first-type barrier layer formed as a sheet-like expanse of high-elastomeric material which is substantially fully self-healing via elastomeric behavior with regard to a piercing projectile wound, adapted to have one side placed directly adjacent such an outside surface,
• a second-type barrier layer disposed contactively adjacent the side of said first-type barrier layer which is opposite said one side as a sheet-like expanse including a body of substantially the same high-elastomeric material utilized for said first-type barrier layer, in which body there in contained a distribution of elemental, bead-like liquid-imbiber components which react, and expand three-dimensionally in relation, to any direct contact with liquid of the above-mentioned certain nature, and
• a third-type barrier layer disposed contactively adjacent that side of said second-type barrier layer which is opposite the side thereof in contact with said first-type barrier layer, with this third-type barrier layer being formed as a sheet-like expanse of substantially the same high-elastomeric material which is employed in said first-type and second-type barrier layers,
• said three barrier layers being dimensioned, with respective layer thicknesses, in a manner whereby said third-type barrier layer possesses a layer thickness which is substantially twice that of said second-type barrier layer.
