Abstract

Composite door systems that are configured for providing safety, security, and resistance to physical impacts or threats (natural and man-caused), and which can be utilized in barrier structures, such as for doors. The composite door systems may include one or more layers, each of which may have one or more fiber layers, such as fabric layers or plastic layers. The composite door systems may further include one or more additional layers of a sheet material, a fill material, or the like. The composite door systems are infinitely customizable and configured to be adapted to a variety of applications, and scalable levels of protection.

Claims (44)

1. A composite door system for a building, the system comprising:

a shell having a front face, a rear face, a first side, a second side, a top side, and a bottom side;

a pre-fabricated composite core, comprising:

a fill material, wherein the fill material provides sound abatement;

one or more support members; and

one or more support member couplings for operatively coupling the one or more support members to the fill material, wherein the one or more support member couplings at least comprise support member adhesive between the one or more support members and fill material;

wherein the one or more support members are at least partially located within the fill material to provide structural support to reinforce the pre-fabricated composite core;

one or more core couplings that operatively couple the pre-fabricated composite core to the shell, wherein the one or more core couplings at least comprise core adhesive between the front face or rear face and the pre-fabricated core;

wherein the pre-fabricated composite core is formed before being assembled to the shell with the one or more core couplings.

2. The composite door system of claim 1 , wherein the pre-fabricated composite core further comprises:

a projectile resistant layer comprising one or more ultra high molecular weight polyethylene (UHMWPE) layers.

3. The composite door system of claim 2 , wherein the UHMWPE layer comprises one or more UHMWPE sheets of UHMWPE fibers bonded together by a bonding material or one or more woven fiber UHMWPE layers.

4. The composite door system of claim 2 , wherein the UHMWPE layer comprises UHMWPE fibers and cementitious material.

5. The composite door system of claim 2 , wherein the UHMWPE layer comprises UHMWPE fibers and cementitious fill liquid that hardens into a solid.

6. The composite door system of claim 1 , wherein the pre-fabricated composite core further comprises:

a projectile resistant layer comprising one or more fabric layers.

7. The composite door system of claim 6 , wherein the one or more fabric layers are formed from a solid mineral material.

8. The composite door system of claim 7 , wherein the solid mineral material is formed from basalt.

9. The composite door system of claim 6 , wherein the one or more fabric layers are formed from aromatic polyamide fibers.

10. The composite door system of claim 1 , further comprising one or more additional layers comprising one or more sheet layers of a porous foam sheet.

11. The composite door system of claim 1 , wherein the one or more support member couplings or the one or more core couplings further comprise fasteners, epoxy, or welds.

12. The composite door system of claim 1 , wherein the fill material is a polystyrene, polyisocyanurate, polyurethane, fiberglass, cellulose, mineral wool, structured kraft paper, plastics, polycarbonates, vermiculite, perlite, cementitious foam, or phenolic foam material.

13. The composite door system of claim 1 , wherein the fill material comprises a foam-in-place material that hardens to create one or move cavities in which at least a portion of the one or more support members are located before the pre-fabricated composite core is operatively coupled to the shell.

14. The composite door system of claim 1 , further comprising:

one or more hardware housings operatively coupled to the shell before assembly of the pre-fabricated composite core.

15. The composite door system of claim 1 , wherein the one or more support members comprise a plurality of support members spaced apart at least partially within the fill material.

16. The composite door system of claim 1 , wherein the one or more support members comprise one or more corrugated shaped support members with the fill material located at least between corrugations of the one or more corrugated shaped support members.

17. The composite door system of claim 14 , further comprising:

one or more projectile resistant materials operatively coupled to the one or more hardware housings, wherein the one or more projectile resistant materials comprise steel or one or more additional fiber layers.

18. The composite door system of claim 1 , wherein the one or more support members comprise z-shaped, c-shaped, tubular shaped, or L-shaped support members.

19. A pre-fabricated composite core, the pre-fabricated composite core comprising:

a fill material, wherein the fill material provides sound abatement;

one or more support members; and

one or more support member couplings for operatively coupling the one or more support members to the fill material, wherein the one or more support member couplings at least comprise support member adhesive between the one or more support members and fill material;

wherein the one or more support members are at least partially located within the fill material to provide structural support to reinforce the pre-fabricated composite core;

wherein the pre-fabricated composite core is configured to be assembled to a shell of a composite door system after being formed through one or more core couplings, wherein the shell comprises a front face, a rear face, a first side, a second side, a top side, and a bottom side, and wherein the one or more core couplings at least comprise core adhesive between the front face or rear face and the pre-fabricated core.

20. A method of forming a composite door system, the method comprising:

forming at least a portion of a shell;

assembling a pre-fabricated composite core, wherein the pre-fabricated composite core comprises:

a fill material, wherein the fill material provides sound abatement;

one or more support members; and

one or more support member couplings for operatively coupling the one or more support members to the fill material, wherein the one or more support member couplings at least comprise support member adhesive between the one or more support members and fill material;

wherein the one or more support members are at least partially located within the fill material to provide structural support to reinforce the pre-fabricated composite core; and

assembling the pre-fabricated composite core to the shell using one or more core couplings, wherein the shell comprises a front face, a rear face, a first side, a second side, a top side, and a bottom side, and wherein the one or more core couplings at least comprise core adhesive between the front face or rear face and the pre-fabricated core.
