Abstract:
1. A transparent armor structure, including: a first layer of a first material; a second layer of a second material, the second layer positioned adjacent to the first layer; a third layer of a third material, the third layer having a first surface, a second surface opposite the first surface, a first edge face having a constant thickness and extending between the first and second surfaces, a second edge face extending between the first and second surfaces, a third edge face opposite the first edge face and having a constant thickness less than the thickness of the first edge face and extending between the first and second surfaces and a fourth edge face opposite the second edge face and extending between the first and second surfaces; an air gap between the second and third layers; a fourth layer of the second material, the fourth layer positioned adjacent to the second surface of the third layer; a fifth layer of the third material, the fifth layer positioned adjacent to the fourth layer, the fifth layer having a first surface, a second surface opposite the first surface, a first edge face having a varying thickness and extending between the first and second surfaces, a second edge face having a varying thickness and extending between the first and second surfaces, a third edge face opposite the first edge face and having a varying thickness and extending between the first and second surfaces and a fourth edge face opposite the second edge face and having a varying thickness and extending between the first and second surfaces; a sixth layer of the second material, the sixth layer positioned adjacent to the fifth layer; a seventh layer of the third material, the seventh layer having a first surface, a second surface opposite the first surface, a first edge face having a constant thickness and extending between the first and second surfaces, a second edge face extending between the first and second surfaces, a third edge face opposite the first edge face and having a constant thickness less than the thickness of the first edge face and extending between the first and second surfaces and a fourth edge face opposite the second edge face and extending between the first and second surfaces, the first surface of the seventh layer positioned adjacent to the sixth layer; an eighth layer of the second material; an air gap between the seventh and eighth layers; and a ninth layer of a fourth material, the ninth layer positioned adjacent to the eighth layer.
