Appl. No.:

13/340181

Inventors:

John Carberry - Talbot TN, US

Assignee:

Schott Corporation - Elmsford NY

International Classification:

F41H 5/26
F41H 5/04

US Classification:

89 3602, 89905, 89908, 89936

Abstract:

A transparent armor system includes a hard face fabricated from a substantially transparent glass-ceramic material exhibiting crystalline bodies throughout the mass of the glass-ceramic material and a backing covering a rear surface of the hard face opposite an anticipated incoming projectile. The backing has a refractive index substantially matching that of the hard face such as to allow substantial transparency of the transparent armor system. The hard face serves to disburse energy caused by the impact of an incoming projectile with the transparent armor system, while the backing serves to retain any pieces of the hard face fractured during ballistic impact. In certain embodiments, a plurality of hard faces are held in parallel and spaced apart arrangement.

US Classification:

89 3602, 89906, 89917, 89910, 89914

Abstract:

An armor system includes a hard face and at least one reinforcing layer covering a rear surface of the hard face. The reinforcing layer is fabricated from a glass-ceramic material exhibiting crystalline bodies throughout the mass of the glass-ceramic material. At least one resilient layer forms a rearward outer layer of the armor system. The hard face and cooperating reinforcing layers serve to disburse energy caused by the impact of an incoming projectile with the armor system, while the resilient layer serves to retain any pieces of the hard face and reinforcing layers fractured during ballistic impact. In certain embodiments, a plurality of hard faces, each with cooperating reinforcing and resilient layers, are held in parallel and spaced apart arrangement.
