Benefits of technology
The invention is a liner for enclosed spaces that is made of a blast resistant composite material. The composite material is a polymer resin matrix with fiber reinforcement. The liner can be fabricated inside the enclosed space and can be a segmented pressure vessel or a collapsible tool. The liner can be used in aircraft cargo holds, room where explosives are stored or processed, or on vehicles or ships. The method of lining a cargo hold with the blast resistant composite material involves fabricating the bulkheads and segments of the liner and attaching them to the floor and walls of the cargo hold. The liner has doorway cutouts that allow for a self-sealing inside door. The technical effects of the invention are improved blast resistance and protection of enclosed spaces from explosions or detonations.
Problems solved by technology
Even a small explosive detonated in the cargo hold during flight will likely destroy the aircraft.

Embodiment Construction
[0019]The inventor has produced a completely new concept for blast protection, enabled in part by employing very different materials than currently used for aircraft, vehicle or building construction. Conventional materials such as thin aluminum or steel provide little or no blast protection. Conventional materials exhibit relatively low specific strength and / or specific modulus. Consequently, blast resistant containers constructed using conventional materials do not offer a weight efficient solution. A new class of materials enables a different approach. Such materials are similar to fiberglass in that they utilize a reinforcing fiber architecture, which is infused with a polymer resin matrix. The most effective version of composite construction utilizes materials which exhibit high compressive and tensile specific strengths and high compressive and tensile specific moduli. Specific strength is defined as the ultimate compressive (or tensile) strength of the material divided by its...

Abstract
The invention is an explosive resistant liner, located inside an enclosed space, and made from a blast resistant material. The liner is preferably constructed inside the enclosed space, consisting of lay-up, curing and assembly steps utilizing a collapsible tool. The invention is particularly applicable to blast protection for aircraft cargo holds.
Description
RELATED APPLICATIONS[0001]This application is a continuation of U.S. application Ser. No. 10 / 979,580, filed Nov. 11, 2004.FEDERALLY SPONSORED RESEARCH[0002]Not ApplicableSEQUENCE LISTING[0003]Not ApplicableBACKGROUND OF THE INVENTION[0004]This invention relates to explosion resistant interior space liners capable of mitigating the shock, overpressure, fragmentation and fire effects of an explosion within the interior space without catastrophic structural or critical systems failure to the building, aircraft or vehicle where the liner is installed. The invention particularly relates to aircraft, specifically installation and operation within cargo holds of commercial air transport category aircraft.[0005]Aircraft are considered to be a likely target for terrorists, based on historical events such as the Pan Am Lockerbie incident, 9 / 11, and other unexplained in-flight disasters that may have been due to terrorist activity. Therefore, it is a major goal of the US Federal Aviation Admin...
