Protective wall structure
First Claim
1. A protective wall structure comprising spaced wall elements including an inner wall element and an outer wall element, said outer wall element being metallic and said inner wall element comprising a multi-layer cloth material, rigidifying means formed of a material selected from the group consisting of precipitation hardened stainless steel, mar-aging nickel steels, alloy steels and titanium alloys having a yield strength of at least about 200 ksi, said rigidifying means being positioned between and contacting said wall elements and forming therewith separated interior spaces, said rigidifying means having a truss-like, zig-zag form including angularly shaped segments which are inclined with respect to one another and to said wall elements, and organic polymerizable material occupying said separated interior spaces together with catalyst means enclosed in rupturable casing means, said casing means preventing contact between said polymerizable material and said catalyst means, the environment of said polymerizable material, including such portions of said catalyst means released on a break of a portion of said rupturable casing means by means producing one or more apertures in said wall elements, being pressurized and said polymerizable material and the portions of said catalyst means released from the casing having the property to co-act on contact to produce a sealant forming a pressurized plug of the one or more apertures in said wall elements.

Abstract
A wall structure characterized by inner and outer wall coverings and positioned therebetween at least one protective inner layer defined by a rib-like formation defining a series of pocket-like spaces between said wall coverings, which spaces embody a protective medium forming with the rib-like formation and said wall coverings a wall structure which is highly resistant to impact, fragmentation or severe damage by piercing. The rib-like formation is of a material selected from the group consisting of precipitation hardening stainless steels, mar-aging nickel steels, alloy steels and titanium alloys and having a yield strength of at least about 200 ksi. The protective medium may include a fire quenching material.
