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.

Glass-ceramic with laminates

A method for producing a ceramic material product. A filler material is provided. The filler material is divided into filler granules collectively having a median diameter approximately 10 microns or less. An amount of carbon is provided. The carbon is divided into carbon particles and the carbon particles are allowed to coat the filler granules. The mixture of carbon-coated filler granules is formed into a selected shape. The formed mixture is placed in a substantial vacuum. The mixture is introduced to a pre-selected amount of silicon and the mixture of carbon-coated filler granules and silicon is heated to a temperature at or above the melting point of the silicon.

Ceramic material product and method of manufacture

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.

Armor system and method of manufacture

A ceramic ballistic material and method of manufacture is disclosed. A filler material is provided. The filler material is divided into filler granules collectively having a median diameter approximately 10 microns or less. An amount of carbon is provided. The carbon is divided into carbon particles and the carbon particles are allowed to coat the filler granules. The mixture of carbon-coated filler granules is formed into a ballistic armor shape. The formed mixture is placed in a substantial vacuum. The mixture is introduced to a pre-selected amount of silicon and the mixture of carbon-coated filler granules and silicon is heated to a temperature at or above the melting point of the silicon.

Ceramic ballistic armor product

The invention is directed to transparent glass-ceramic materials for use in transparent armor systems. Applications include armor systems for ground vehicles and aircraft as well as personal protective equipment. The glass-ceramic materials according to the invention exhibit a ballistic limit vs. areal density line slope of 1.0 or greater, preferably 1.1 or greater and more preferably 1.2 or greater. The crystalline phase of the glass ceramic materials may include &#x3b2;-quartz, spinel, spinel solid solutions, mullite and phases known in the art to be transparent.
