Description

Composite bulletproof plate for building and construction Request priority The present application claims priority from U.S. provisional patent application Ser. No. 63/578,546, attorney docket No. 1202317, filed 24 at 8 of 2023, incorporated herein by reference in its entirety. Technical Field The present disclosure relates to sheet products including composite ballistic panels. Background Armor (armor) or ballistic resistant materials are increasingly used in modern applications. Armor has historically been generally in the form of sheet metal, the thickness of which varies depending on the type of ammunition the design is intended to intercept. As the metal armor becomes thicker, its weight increases significantly. Thinning the metal armor while reducing the weight will also reduce the ability of the armor to intercept the target ammunition. Other engineering materials such as ceramics have been used as armor. However, these materials are also heavy and can be prohibitively expensive. In addition, these materials are often difficult to shape and may require expensive molds and dies. There is a need in the art for lightweight ballistic panels that can be used in permanent or temporary structures such as walls, doors, roofs, floors, protective barriers (barriers) and fences. Disclosure of Invention Disclosed herein are sheet products comprising composite ballistic resistant panels.
