Abstract:
A barrier for containing an explosion in an enclosure such as a room, said barrier being a structural panel comprising:a base sheet;a plurality of truncated polyhedral elements secured to and projecting from said base sheet; anda face sheet covering and secured to the truncated apexes of said polyhedral elements, said face sheet being constructed to disintegrate or separate from said polyhedral elements to expose them when subjected to the pressure wave of an explosion;each of said polyhedral elements being constructed to collapse when subjected to the pressure wave of an explosion, being filled with a liquid, and having an opening therein that is closed by a closure device that is openable or removable in response to the collapse of the polyhedral element caused by the explosion, said opening being of a size to effect a misting action of the liquid when it is ejected from said opening by the collapse of said polyhedral element;whereby upon the occurrence of an explosion in the enclosure, the pressure wave thereof causes the removal of said face sheet and the collapse of said polyhedral elements which generates a liquid mist surrounding the enclosure to absorb and dissipate the heat and energy of the explosion.
