Composite door systems are provided for use in a protective barrier structure. The composite door systems provide for quick assembly, safety, security, and resistance to physical impacts or threats. The composite door systems may include a shell and a core that can be factory completed or finished on site. The shell may be shipped to the assembly location of the barrier structure, and the core may be formed on site by pouring liquid fill material into a cavity of the shell, which is allowed to cure into a solid fill material. Hardware housings may be operatively coupled to the shell that are made to receive door hardware but resist the liquid full material from filling the hardware housings. The shell, core, and/or hardware housings may provide resistance to damage, such as projectiles to provide enhanced security protection to the occupants or contents of the building structure.

Barriers may utilize cores that may be pre-assembled and dropped into a barrier or may be formed within the barriers. The cores may include traditional core materials, biomass materials, graphite polystyrene (GPS) material, or other types of materials. The core may be formed from one or more layers, such as one or more stiffener layers (e.g., stiffener panel, stiffener rods, or the like), one or more matrix layers (e.g., with apertures extending therein), one or more solid layers (e.g., wood, plastic, composite, foam, fiber, or the like), one or more fluid sealed layers (e.g., air, argon, nitrogen, or other like), and/or other types of layers. The barrier edge members, the faces, and/or the core layers described herein may be assembled to each other in traditional ways, such as welding, and/or may be assembled to each other in a way that reduces the amount of welding and/or use of steel.
