Abstract:
1. A method for applying a plural-layer coating to the outside of a liquid container to act as an anti-leakage barrier in the event of a penetration wound occurring in the container resulting from a penetrating projectile strike, said method comprising forming on the outside surface of such a container, a first, non-composite barrier layer which is optimized for providing principally an elastomeric wound-closure response regarding the occurrence of such a strike, where the elastomeric response of this layer is furnished by an elastomeric material selected from the group consisting of thermoplastic materials, thermoset materials, flexible PVC materials, latex rubber materials, nitrile rubber materials, and urethane materials, and forming on the outside of such a first layer a second, composite-material barrier layer which is optimized for combined elastomeric and independent liquid-imbibing wound-closure responses regarding the occurrence of such a strike, where the elastomeric response of this layer is furnished by an appropriate elastomeric material, and the liquid-imbibing response is furnished by appropriately chosen, embedded, liquid-imbiber elements, and forming on the outside of such a second layer a third, non-composite barrier layer which is optimized for providing principally an elastomeric wound-closure response regarding the occurrence of such a strike, and where the elastomeric response of this layer is furnished by an elastomeric material which is also selectively drawn from the same list of elastomeric materials expressed above in relation to the mentioned first layer.
