A thermal barrier fabricated from pumice, or pumice-like material, and a suitable binder is provided. It may be formed as a self-supporting or load-bearing structural member, or as a thick coating for IR signature reduction. A first embodiment may be used to build a structure, e.g., a room onboard a ship that serves as an effective thermal barrier. Should a fire start in the room, the thermal barrier prevents rapid spreading of the fire and provides crews additional time to fight the fire. A second embodiment, as a thick coating, reduces the IR signature of a radiating body, such as an exhaust stack, by a factor of four. This thick coating helps shield an object from IR surveillance devices or seekers, resulting in much shorter acquisition and tracking times for these IR devices and seekers. In addition to benefits as a thermal barrier, structural members using concepts disclosed for this invention may provide inherent blast and shock resistance.

Thermal barrier and method of use

A material for use in containers for explosive media and a material for use n containers for absorbing the dynamic shock of an explosion and prevent sympathetic detonation of adjacent explosive devices in which the material is a relatively lightweight, porous, shock absorbing material mixed with a binder to provide a castable composite. A storage container receives the cast filler and is thereby hindered from being subjected to destruction from sympathetic detonation due to donor detonation within the storage container or a proximate storage container.

A compact, reliable, nonincendiary fireline cord detonator is disclosed which attaches without tools to a length of explosive fireline cord utilized to clear a path through a wooded or brush covered area. The detonator uses an exploding bridgewire squib to protect against a premature explosion caused by static electricity or electric current induced by spurious electromagnetic radiation.

A continuous rod warhead which utilizes ribbon shaped rods plug welded toher at alternate ends to form a continuous rod bundle is used in terrain clearance. The warhead may either be dropped from an aircraft and contact exploded or hand placed and then exploded by any convenient means.
