US12352541 - Layer composite door systems

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.

The patent describes a composite door system designed for enhanced safety and security, featuring a customizable structure with multiple layers, including fiber and fill materials for sound abatement. The system incorporates a pre-fabricated composite core that is reinforced with support members and adhesive couplings, allowing for scalable protection in various applications.

Claim 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. 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; 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.
