Patent attributes
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.
