BALLISTIC AND FIRE PROTECTION ENCLOSURES

摘要

A fire-resistant, projectile-resistant, composite-material panel for use in a modular concrete enclosure may include a panel body having a front major face and a back major face opposite the front major face. The panel body may include concrete and a plurality of round objects embedded within the concrete and configured to hinder the advance of projectiles through the panel body, with each of the round objects having a dimension in a range of 0.25-1.0 inches. The panel may further include a resin layer disposed over the front major face, the resin layer configured to bind the front major face of the panel body when struck by projectiles, and a fire-resistant layer disposed over the back major face. The fire resistant layer may be configured to protect an interior space of the enclosure against fire exterior to the enclosure.
