Abstract
A lightweight composite panel for use in constructing a portable or mobile enclosure capable of resisting penetration by small arms projectiles, explosive forces and heat having a multi-layered sandwiched construction. The layers include spaced apart metal panels with a honeycomb structure filled with a subliming material, a panel of projectile resisting material, and at least one panel of yieldable thermal insulation material disposed therebetween.

A lightweight composite panel for use in constructing a portable or mobile enclosure capable of resisting penetration by small arms projectiles, explosive forces and heat, comprising:
- a first metal panel;
- a second metal panel spaced in substantial parallelism to the first metal panel;
- a honeycomb configured panel disposed between the first and second metal panels in abutment to the first metal panel and oriented with the walls of the honeycomb configuration generally perpendicular to the first metal panel;
- a subliming material at least partially filling the cell structure of the honeycomb configured panel;
- a panel of lightweight projectile resisting material disposed between the honeycomb configured panel and the second metal panel;
- means for venting gas produced by the subliming material from the cell structure of the honeycomb configured panel;
- and,
- a panel of yieldable thermal insulation material sandwiched between and in abutting juxtaposition to both the panel of lightweight projectile resisting material and the second metal panel.
