Abstract
A method for spray-creating a composite-material layer on the outside surface of a liquid container to defeat liquid leakage following a projectile penetration of the container. The method includes (a) defining a by-weight percentage blend of two penetration-reaction materials, where the contribution of one such material, an initially liquid and wet-sprayable, but subsequently curable-to-dry, high-elastomeric body-forming material, is larger than that of the other material, which takes the form of a population of dry, liquid-imbibing bead elements, (b) creating weight-percentage-differentiated, simultaneous sprays of these two materials for contact-blending, during spraying, into a composite spray en route in the air toward the region of a target liquid container, and (c) as a part of such creating, controlling the amount of en route, inter-material, contact blend time between the two materials.
