Hybrid hardened ballistic security door
An innovative ballistic door is disclosed that is destined for use in schools, offices and building structures. The innovative door comprises a hybrid ballistic core, comprising at least two sections, wherein one section is a heavy impact resistant material rated to NIJ level III strength to resist rounds fired from high-powered rifles, as well as resisting breaches from explosive devices such as pipe bombs and the like. AR500 steel plate having a thickness of ¼ inch meets this requirement. The remaining sections of the innovative ballistic hybrid core comprise at least one lighter-weight ballistic sheet material, such as E Glass fiber composite sheet, which at least comply with the NIJ level IIIA standard. This E Glass material is ideally suited to resist the impact of a pipe bomb explosion. The novel ballistic core construction allows a compromise between protective and practical weight requirements. In addition, the innovative ballistic door provides for substantial anti-breach protection of the latch and lock mechanism and hinges.
