Patent number: 9091510Abstract: 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. In certain embodiments, a bonding layer is provided to bond the backing to the hard face. 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.Type: GrantFiled: March 21, 2007Date of Patent: July 28, 2015Assignee: Schott CorporationInventors: John Carberry, George D. Forsythe, Katherine T. Leighton

Patent number: 6376431Abstract: A carbon/carbon (C/C) composite comprising crystalline silicon carbide which is essentially uniformly distributed on both internal and external surfaces of the composite in a low concentration, as well as a process for producing the composite and the use of the composite in brake materials for industrial roll goods, automotives, trucks, trains and aircrafts. It has been discovered that small amounts of crystalline silicon carbide uniformly distributed throughout the carbon/carbon composite results in reduced wear with either no change or a slight increase in the friction coefficient.Type: GrantFiled: March 15, 2001Date of Patent: April 23, 2002Assignee: Honeywell International Inc.Inventors: Roger L.
