Patent number: 9334378Abstract: A reinforcing fiber for reinforcing a transparent matrix composite. The fiber includes a substantially transparent fiber ribbon having an elongated cross-sectional geometry. The fiber ribbon includes edges that are substantially opaque. Light is substantially prevented from passing through the opaque edges to reduce or eliminate light distortion through the fiber. A composite utilizing the reinforcing fibers and a method for making a window assembly and a method for manufacturing a vehicle are also disclosed.Type: GrantFiled: January 16, 2008Date of Patent: May 10, 2016Assignee: The Boeing CompanyInventors: Adam J. Lang, Mark S. Wilenski, Alan M. Markus, Larry A. Godby

Patent number: 8141393Abstract: A glass fiber and a method of manufacturing a glass fiber for reinforcing a transparent composite matrix is disclosed. The glass fiber includes a first glass material having a first refractive index, a first modulus, and a first durability characteristic and a second glass material having a second refractive index, a second modulus, and second durability characteristic. The second durability characteristic is greater than the first durability characteristic. Durability characteristic is selected from the group comprising resistance to chemical attack, resistance to acid attack, resistance to fading from exposure to ultra-violet radiation, and resistance to mechanical abrasion.Type: GrantFiled: June 2, 2011Date of Patent: March 27, 2012Assignee: The Boeing CompanyInventors: Mark S.

Patent number: 8132430Abstract: A glass fiber and a method of manufacturing a glass fiber for reinforcing a transparent composite matrix are disclosed. The glass fiber includes a first glass material having a first set of mechanical properties including a first modulus and a first coefficient of thermal expansion (CTE) and a second glass material having a second set of mechanical properties including a second modulus and a second CTE. The second glass material forms a substantially uniform coating on the first glass material. The second CTE is less than the first CTE. The glass fiber is formed by reducing the cross-section of a glass fiber preform of the first glass material coated with the second glass material by hot working. Because of the selected difference in the CTE's, the first glass material imparts a compressive force upon the second glass material, which improves the strength of the glass fiber.Type: GrantFiled: June 2, 2011Date of Patent: March 13, 2012Assignee: The Boeing CompanyInventors: Mark S. Wilenski, Adam J. Lang, Alan M. Markus, Larry A. Godby

Patent number: 8057721Abstract: A resin infusion mold tool system for use in a vacuum assisted resin transfer molding process with a subsequent pressure bleed step. The mold tool system includes a mold assembly having an outer mold line tool connected to resin supply lines and supplying resin to the preform. A plurality of inner mold line tools form a hard interface with the inner mold line of the fiber preform and are held to within tight tolerances by an external locating fixture. Excess resin is drawn out of the fiber preform using a vacuum bag connected to vacuum lines and disposed over the inner mold line tools but not between the tools and the fiber preform. The mold assembly is placed in an autoclave, the resin supply lines are detached and the autoclave pressurized to bleed additional resin out of the preform to raise the fiber volume of the composite structure.Type: GrantFiled: February 13, 2008Date of Patent: November 15, 2011Assignee: The Boeing CompanyInventors: Patrick J. Thrash, Roger Alan Burgess, Alan M. Markus
