Abstract

The present invention provides structural insulated panels which may afford protection from blast and ballistics events. The inventive structural insulated panel comprises a metal sheet, a polyurethane or polyisocyanurate foam and a polycarbonate sheet, film or laminate. Due to the materials of their construction, the inventive panels are light weight and a plurality of such panels may be quickly and easily assembled into sturdy, insulated, temporary or permanent shelters for protection in a variety of situations and environments.

First claim

What is claimed is:

1. A structural insulated panel comprising:
a metal sheet;
a polyurethane foam having a first side and a second side; and
a polycarbonate sheet, film or laminate,
wherein the foam adheres the first side to the metal sheet, and adheres the second side to the polycarbonate sheet, film or laminate, and
wherein the foam consists of:
one or more isocyanates,
one or more polyols consisting of one or more polyester polyols and one or more polyether polyols,
a blowing agent, and
optionally, one or more compounds selected from the group consisting of:
surfactants, catalysts, pigments, colorants, fillers, antioxidants and flame retardants.

2. The structural insulated panel according to claim 1 , wherein the metal is selected from the group consisting of steel, aluminum, iron, copper, tin, lead, nickel, brass, titanium, zinc and alloys thereof.

3. The structural insulated panel according to claim 1 , wherein the panel has ballistics resistance.

4. The structural insulated panel according to claim 1 , wherein the panel is framed with one or more materials selected from the group consisting of wood, metal, and composites.

5. The structural insulated panel according to claim 1 further including one or more signal defense films.

6. A structure comprising a plurality of structural insulated panels, each panel comprising a metal sheet, a polyurethane foam having a first side and a second side, and a polycarbonate sheet, film or laminate, wherein the foam adheres the first side to the metal sheet, and adheres the second side to the polycarbonate sheet, film or laminate, and wherein the foam consists of: one or more isocyanates, one or more polyols consisting of one or more polyester polyols and one or more polyether polyols, a blowing agent, and optionally, one or more compounds selected from the group consisting of: surfactants, catalysts, pigments, colorants, fillers, antioxidants and flame retardants.

7. The structure according to claim 6 , wherein the metal is selected from the group consisting of steel, aluminum, iron, copper, tin, lead, nickel, brass, titanium, zinc and alloys thereof.

8. The structure according to claim 6 , wherein the panel has ballistics resistance.

9. The structure according to claim 6 , wherein the panel is framed with one or more materials selected from the group consisting of wood, metal, and composites.

10. The structure according to claim 6 further including one or more signal defense films.

11. The structural insulated panel according to claim 1 , wherein the foam adheres the first side to the metal sheet, and adheres the second side to the polycarbonate sheet, film or laminate, without mechanical fasteners.
